chore(deps): Update to Yarn v4, Node.js v18, and fix a broken dependency

[donmccurdy]

Changes in preparation for the update to glTF Transform v4. glTF Transform v4 requires a newer version of Sharp for texture compression, which in turn uses WebAssembly to support Deno environments and has some important changes to its installation process:

In general things should 'just work' for most users, but support for npm <10, yarn <3, and node.js <18 has been dropped. I've omitted the update to glTF Transform from this PR, and included only the infrastructural changes.

Based on https://sharp.pixelplumbing.com/install it sounds like Yarn v1 is still supported, but on maintenance mode. So hopefully that part won't be an issue for users, but I think it's worth going ahead and updating the Yarn version used in this repo.

@donmccurdy i updated all dependencies and published, im using the yarn 1 fallback atm. im kind of scared updating to a later yarn due to work projects. is there a way to fix the cli or let it use yarn-latest without forcing the project to use a specific tool?

[donmccurdy]

Sharp hasn't forced a specific tool here — it allows anything except Yarn v1, or the mentioned workaround for Yarn v1. But yeah, probably a lot of people still using Yarn v1. It'd also be OK to upgrade everything except Sharp, and pin that at v0.32 indefinitely. I've been gradually switching my own projects to Yarn v4, which has been fine as long as I use nodeLinker: node-modules.

[donmccurdy]

@drcmda OK, let's merge #253 as a starting point then, to un-break package.json. I'll look into whether we can upgrade to glTF Transform v4 here without upgrading from Yarn v1.
