Try biome for formatting

Description

Try and use Biome for formatting instead of Prettier, in an attempt to make things faster and resilient to not-so-well-formed code.

Beware that we are using prettier plugins and those features should remain available (namely, import sorting).

While formatting itself works, there is still no support for import sorting that matches the existing behaviour. That is being added in biomejs/biome#3177
