feat: support out-format as args

[jrehwaldt]

This PR adds support for --out-format as supported arguments.

when not set, behavior is unchanged and the github-actions format is added.
When set, and github-actions is not given, it is added as the first output, otherwise, it is not added.
Any other provided format is preserved.

Fixes #458
Fixes #362
Closes #613

Unfortunately, the code contains a bug. The resulting argument for

      - name: golangci-lint
        uses: golangci/golangci-lint-action@322510a3eacd2fcb0ad853cfdb7573089cf4995e
        with:
          version: 1.20
          working-directory: ./scripts/go
          args: --issues-exit-code=0 --out-format=checkstyle:golangci-lint-report.xml

is

/home/runner/golangci-lint-1.53.2-linux-amd64/golangci-lint run --out-format=checkstyle:golangci-lint-report.xml,github-actions --path-prefix=./scripts/go --issues-exit-code=0 --out-format=checkstyle:golangci-lint-report.xml

It contains the --out-format argument twice, overruling the fist parameter.

Yes I missed that

I guess a const userArgsStripped = userArgs.replaceAll(/--out-format=.+?(?=\s)/, "") might do. This is actually wrong for cases when the out-format arg is the last argument and your regex using \S much better.

I was also wondering if the new code will concatenate "" with "github-actions" resulting in a string --out-format=,github-actions (note the comma) when no arg --out-format is given. Nevertheless, I did not try that.

No, I already checked that.
