trunk fmt does not surface `biome format` errors

[sxlijin]

👋 hullo!

trunk doesn't appear to surface biome format errors, not sure why, haven't dug into it. still on WSL.

here's a malformed biome config that complains correctly when run with pnpm biome format .:

❯ cat biome.json
{
        "$schema": "https://biomejs.dev/schemas/1.7.3/schema.json",
        "organizeImports": {
                "enabled": true
        },
        "linter": {
                "enabled": true,
                "rules": {
                        "recommended": true
                }
        },
        "formatter": {
                "enabled": true,
                "rules": {
                        "recommended": true,
                        "formatWithErrors": true,
                        "indentStyle": "spaces",
                        "indentWidth": 2,
                        "lineEnding": "lf",
                        "lineWidth": 120
                }
        },
        "javascript": {
                "formatter": {
                        "quoteStyle": "single",
                        "jsxQuoteStyle": "single",
                        "semicolons": "asNeeded",
                        "trailingComma": "all"
                }
        }
}

Howdy! 😄

Did a quick investigation and looks like this case is getting swallowed up in the exit code 1 output. I'll put up a fix for this, but in the meantime you can override with:

lint:
  definitions:
    - name: biome
      commands:
        - name: fmt
          success_codes: [0]

Unfortunately we can't do this for the lint subcommand easily because it's a regex linter and all biome errors and diagnostics output an exit code 1. Nevertheless, fixing this for format should be sufficient! Thanks for flagging this!
