[Feature request] Allow adding PR reviewers via `publish:github:pull-request` action

We’d like to be able to add reviewers to PRs created by Backstage via the publish:github:pull-request action by setting them as parameters of the action.

Feature Suggestion

We’d like to have two extra parameters on the publish:github:pull-request action, reviewers and teamReviewers, which would allow us to add reviewers much more easily to Backstage-created PRs just by adding them to the action definition:

    - id: pullrequest
      name: Create pull request
      action: publish:github:pull-request
      input:
        repoUrl: ${{ parameters.repoUrl }}
        branchName: ${{ parameters.branchName }}
        title: New Pull Request
        description: A newly created PR on GitHub
        reviewers:
          - user1
        teamReviewers:
          - team1

Possible Implementation

Currently, we have put together this code to perform this task:

const octokitIntegration = await new OctokitProvider(scmIntegrations).getOctokit(REPOSITORY_URL);
const prUrlSegments = pullRequestUrl.split("/");
await octokitIntegration.client.rest.pulls.requestReviewers({
    owner: octokitIntegration.owner,
    repo: octokitIntegration.repo,
    pull_number: parseInt(prUrlSegments[prUrlSegments.length-1]),
    reviewers: [...],
    team_reviewers: [...]
});

where pullRequestUrl is the remoteUrl of the PR as returned by the publish:github:pull-request action.

Context

We are using the publish:github:pull-request action in our scaffolding process to propagate the creation of the new project to other repositories (mainly IaC-related) by sending PRs. We need to add a team as a reviewer of these PRs so that those people get notified when Backstage sends a PR.

@benjdlambert Can this be reopened? The feature request is still valid.
