Create configs when untracked repos found

[cuba0001]

Related to #2582

According to the discussion in the previous #2611 it creates missing toml files. I added an exit code 2 to signal that untracked repos are found and configs are created, because this is the simplest way for the workflow to handle it. This still keeps code 1 for unexpected errors.

Hi, thanks for the PR! I quickly glanced at the YAML file only, left one comment.

The branch name is a constant, same as in josh-sync. I don't think we need this lookup complexity.

1. Run the team command and check if any TOML file was generated, according to its exit code
2. If yes, create the new branch, add the TOML files, commit it, and push to the branch
3. If a PR does not exist at the moment, create it from that branch

[cuba0001]

Just to clarify. Should the team command run from the automation branch or from main? This was the main point I was unsure about.

If we run it from main, there is a problem. If an infra-admin makes changes between the first and second workflow runs, those changes will be overwritten because we would have to force-push the branch, as each run would detect the same untracked repositories again (not the same for automation branch, because missing configs are already commited).

Is this ok?

As for dynamic branch name, I added it to avoid making the same branch actual in every workflow run, since it could fall far behind main if nobody rebases it or something.

[Kobzol]

I'd say that it should always run from main. If there is a diff, then force push to the branch. If there is no diff, and a PR is open, then close the PR (unless that somehow prevents us from opening a PR from the same branch in the future).

[cuba0001]

Done. It force pushes the automation branch if PR exists, its name is constant. Also, deletes PRs which are open and there is no diff.

This PR was rebased onto a different main commit. Here's a range-diff highlighting what actually changed.

Rebasing is a normal part of keeping PRs up to date, so no action is needed—this note is just to help reviewers.

Sorry for the dealy. I force-pushed improvements.
