feat: biome organize imports

[igorlfs]

Hello!

This PR adds another biome formatter, to only organize imports (in a similar manner to ruff, with ruff's organize-imports).

The major reason for another formatter is that there are some known limitations when using biome's regular formatter with HTML super languages, such as Svelte and Vue.

Uh, I just realized I can achieve the same result by disabling formatting, inside Biome's configuration. Specifically, here's the snippet for my use case (Svelte):

"formatter": {
        "enabled": true,
        "ignore": [
            "**/*.svelte",
        ]
    }

Coupled with the biome-check formatter, this only organizes imports.

I was considering closing this PR, but I noticed it was mentioned elsewhere, and it would close #585 (I guess)

How would you expect this formatter to be used, and is the use case different from the biome-check formatter?

biome-check is used for formatting and sorting imports. However, in some situations (e.g., using a language such as Svelte), formatting has some limitations that make it not so useful (see OP). To handle this situation, one can either configure biome to NOT format such files (but sort their imports), or we could provide this additional formatter, so users don't need to manually configure biome.

Sounds reasonable to me. Thanks for the PR!
