[AssetMapper] Add FAQ for code lint/format

Hi everyone,

Little self-promotional PR for AssetMapper, to indicates how users can lint and format their front assets when using the fresh [`kocal/biome-js-bundle`](https://github.com/Kocal/BiomeJsBundle).

It's a bundle around Biome.js, a (much) faster linter (than ESLint) and formatter (than Prettier), which does not requires any configuration to handle JS/TS, JSX/TSX, CSS files... and soon Vue/Svelte files.

Thanks!
