Subject: [PATCH] feat(extras): add biome formatter (#4448)

## Description
This PR adds biome as a conform/null-ls formatter.

When using biome lsp formatting directly, the syntax highlighting is
flickering. However, it works great when formatting is configured with
conform.

To avoid conflicts with Prettier, it is recommended to set
`vim.g.lazyvim_prettier_needs_config = true` In this case, both prettier
and biome formatters could be activated simultaneously.
