Migrating from create-react-app to vite

[Pelsin]

This PR aims to migrate from create-react-app(CRA) to vite as CRA is no longer recommended. Since CRA has been stale for awhile we have a lot of deprecated dependencies:

Bundle before:

Bundle after:

Also changes files to .jsx which should make the bundling faster, it also helps us if we want to start migrating some of the files to TS further down the line, and helps the intelliSense that went bananas on some earlier files that where .js but had some TS in them.

The dev server has been converted to esm and also gets the .env which did not work before.

linting in CRA was quite opinionated and the one in this pr is using lots of defaults.
@FeralAI do you have some suggestions on rules that should be added?

I started out rewriting everything to TS but that was quite overwhelming(main...Pelsin:GP2040-CE:vite-typescript), so decided to make this PR and breaking it up best to my abilities.

Sorry for the wall of text and big PR!

This looks great @Pelsin! Tested it out and everything is working, along with the reduced bundle size 😄

Regarding the eslint rules, I ran npx eslint --ext .jsx,.js src/ and just about everything that's an error is something that should be addressed. We don't run the lint rules on build, so this PR won't break builds and doesn't need to address the errors.

The only rule I might want to add would be turning off no-extra-boolean-cast. There's a pattern for converting form values that uses this and I want to say it was for a reason, but don't recall what that was. I guess once this is merged we can test out removing/reworking those checks.

@FeralAI Nice, thanks for the quick review!

Added the no-extra-boolean-cast rule 👍
Makes sense with the linting tho, if we don't run it on build. After the boolean cast rule there is not many errors left so maybe we can add it to the build process soon :D

Resolved conflict so should be good to go then!

Looks solid! Will be cool to get our webpage up to a more modern framework.
