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.
