Chore: Find alternatives ESLint + Prettier

[Hugos68]

ESLint + Prettier not only are quite slow to being with, they're also very cumbersome to setup together. Solutions like Biome solve this by having 1 dependency take care of all workspace related styling. This is just a free "win". However Biome currently doesn't support HTML-ish language (Svelte, Vue) and MDX. These are blockers because they are used heavily throughout Skeleton's monorepo.

We should monitor https://biomejs.dev/internals/language-support/ to see when all of our missing languages are supported. Note that all of these languages won't be plugins with config etc, it's all build in, one of the many great things Biome accomplishes.

Update:

We've replaced eslint with oxlint and our linting times went from 20 seconds to 2 seconds (10x) while being type aware, meaning more easy issues were catched. oxc, the author of oxlint will bring a formatter aswell most likely eof/next year, we should aim to migrate to that formatter when it is released and supports the neccesary files we need it to support.
