Currently, Buf GitHub actions steps parses the CLI output.
https://github.com/bufbuild/buf-lint-action/blob/eb3d81d31cf26ca507ffc24e1132cff1f3c29e95/src/run.ts#L131

I would like to have --error-format=github-actions in the CLI (just like golangci )

In my case, I have a custom github-actions step that uses the CLI directly, and I don't want to parse the output myself.
