Add rmdepcheck and fedora-review tests

[LecrisUT]

TODO:

• Write new tests or update the old ones to cover new functionality.
• Make the related tests compatible with packit's contexts
  • rmdepcheck
  • fedora-review

Merge after fedora-ci/rmdepcheck-pipeline#12

Also not sure how this would behave when run in prod when the corresponding tests are not yet enabled.

RELEASE NOTES BEGIN

Packit Fedora-CI now runs rmdepcheck and fedora-review tests on PRs.

Code Review

This pull request introduces support for rmdepcheck and fedora-review tests within the Fedora CI workflow by adding dedicated payload generation methods and updating the corresponding integration tests. The review feedback identifies several necessary corrections: the TMT plan names in the implementation should include a leading slash to maintain consistency with conventions and test expectations; the integration tests must be updated to expect the stg branch for the ref field to match the non-production environment logic; and the deployment check should be refactored to compare the enum member directly rather than its string name for improved robustness.
