[Feature]: support biome for jest-snapshot formatting

[mnahkies]

🚀 Feature Proposal

Detect and use biome (https://biomejs.dev/) for the formatting/indentation of inline snapshots generated by jest-snapshot

Alternatively, throw an exception when:

• No prettier package is installed/found
• And, prettierPath is undefined (eg: not explicitly set to null)

Motivation

I've recently migrated some projects from using prettier to biome for formatting, which in inadvertently broke the indentation of jest inline-snapshots.

This wasn't immediately apparent/obvious, and it was only stumbling across https://github.com/jestjs/jest/issues/14305 that made me realize that removing prettier as a dependency had caused this.

Example

No response

Pitch

I appreciate from looking at the PR implementing support for prettier@3 that introducing first class biome support might be more complexity / core bloat than it's worth (though I do think it would be nice).

The alternative of throwing an error though would've saved me a lot of confusion / frustration - I had no idea that jest-snapshot relied on prettier, and since the snapshot indentation changes only happened when snapshots needed updating, there was a gap between the break being introduced and being visible.

(ie: https://github.com/mnahkies/openapi-code-generator/pull/129/files#diff-64237f590faccbee856b106612fd72c8d370d7bd5aafc38c489f62b692344617 replaced prettier with biome, but the snapshots were not altered yet)

Not stale

Yeah, I don't have any interest in supporting Biome out of the box (unless it's trivial - happy to take a PR in that case).

Why can you not set it to null?

EDIT: I guess you might not know you need to - I don't think the loss of auto indented snapshots for prettier users are worth supporting the waaay lower user base of biome. Happy to take ideas in how to improve the experience.
