bug: incorrect language tag for JavaScript

[EshaanAgg]

In many of the .mdx files containing the documentation, the JavaScript code snippets have been marked with the language tag JavaScript as follows:

This tag is incorrect and should be replaced by javascript. These incorrect language tags lead the build by Shiki to not be rendered as JS, but rather plaintext:

A simple global search and replacing [triple backticks]JavaScript with [triple backticks]javascript should fix the same.

I can take this issue up if the maintainers approve.

just a quick note here that the majority of these are in src/content/contributor-docs, which have to be fixed in the p5 repo and then re-imported here with the build contributor docs script. i see a few in src/content/tutorials, which can be fixed directly in this repo.

For those in contributor docs, we'll fix in the p5.js repo.
