web: bump the esbuild group across 1 directory with 2 updates

[dependabot]

Bumps the esbuild group with 2 updates in the /web directory: @esbuild/darwin-arm64 and @esbuild/linux-arm64.

Updates @esbuild/darwin-arm64 from 0.19.5 to 0.21.3

Release notes

Sourced from @​esbuild/darwin-arm64's releases.

v0.21.3

• Implement the decorator metadata proposal (#3760)

  This release implements the decorator metadata proposal, which is a sub-proposal of the decorators proposal. Microsoft shipped the decorators proposal in TypeScript 5.0 and the decorator metadata proposal in TypeScript 5.2, so it's important that esbuild also supports both of these features. Here's a quick example:

  // Shim the "Symbol.metadata" symbol
  Symbol.metadata ??= Symbol('Symbol.metadata')
  const track = (_, context) => {
  (context.metadata.names ||= []).push(context.name)
  }
  class Foo {
  @​track foo = 1
  @​track bar = 2
  }
  // Prints ["foo", "bar"]
  console.log(Foo[Symbol.metadata].names)

  ⚠️ WARNING ⚠️

  This proposal has been marked as "stage 3" which means "recommended for implementation". However, it's still a work in progress and isn't a part of JavaScript yet, so keep in mind that any code that uses JavaScript decorator metadata may need to be updated as the feature continues to evolve. If/when that happens, I will update esbuild's implementation to match the specification. I will not be supporting old versions of the specification.

• Fix bundled decorators in derived classes (#3768)

  In certain cases, bundling code that uses decorators in a derived class with a class body that references its own class name could previously generate code that crashes at run-time due to an incorrect variable name. This problem has been fixed. Here is an example of code that was compiled incorrectly before this fix:

  class Foo extends Object {
    @(x => x) foo() {
      return Foo
    }
  }
  console.log(new Foo().foo())

• Fix tsconfig.json files inside symlinked directories (#3767)

  This release fixes an issue with a scenario involving a tsconfig.json file that extends another file from within a symlinked directory that uses the paths feature. In that case, the implicit baseURL value should be based on the real path (i.e. after expanding all symbolic links) instead of the original path. This was already done for other files that esbuild resolves but was not yet done for tsconfig.json because it's special-cased (the regular path resolver can't be used because the information inside tsconfig.json is involved in path resolution). Note that this fix no longer applies if the --preserve-symlinks setting is enabled.

v0.21.2

• Correct this in field and accessor decorators (#3761)

  This release changes the value of this in initializers for class field and accessor decorators from the module-level this value to the appropriate this value for the decorated element (either the class or the instance). It was previously incorrect due to lack of test coverage. Here's an example of a decorator that doesn't work without this change:

  const dec = () => function() { this.bar = true }

0.19.11

• Fix TypeScript-specific class transform edge case (#3559)

  The previous release introduced an optimization that avoided transforming super() in the class constructor for TypeScript code compiled with useDefineForClassFields set to false if all class instance fields have no initializers. The rationale was that in this case, all class instance fields are omitted in the output so no changes to the constructor are needed. However, if all of this is the case and there are #private instance fields with initializers, those private instance field initializers were still being moved into the constructor. This was problematic because they were being inserted before the call to super() (since super() is now no longer transformed in that case). This release introduces an additional optimization that avoids moving the private instance field initializers into the constructor in this edge case, which generates smaller code, matches the TypeScript compiler's output more closely, and avoids this bug:

  // Original code
  class Foo extends Bar {
    #private = 1;
    public: any;
    constructor() {
      super();
    }
  }
  // Old output (with esbuild v0.19.9)
  class Foo extends Bar {
  constructor() {
  super();
  this.#private = 1;
  }
  #private;
  }
  // Old output (with esbuild v0.19.10)
  class Foo extends Bar {
  constructor() {
  this.#private = 1;
  super();
  }
  #private;
  }
  // New output
  class Foo extends Bar {
  #private = 1;
  constructor() {
  super();
  }
  }

• Minifier: allow reording a primitive past a side-effect (#3568)

  The minifier previously allowed reordering a side-effect past a primitive, but didn't handle the case of reordering a primitive past a side-effect. This additional case is now handled:
