[dx] use Biome instead of Prettier, part 1 (#2729)

Biome seems to be MUCH faster than Prettier. Unfortunately, it
introduces some formatting changes around the ternary operator, so we
have to update files in the repo. To make revert easier if we need it,
the change is split into two PRs. This PR has only config/package
changes and is expected to fail the CI.
