Standard test Roles: Clone repo at the same branch

[Miro Hrončok]

Hello CI folks!

Suppose I have this in my tests.yml:

	
     repositories:
     - repo: "https://src.fedoraproject.org/rpms/pyproject-rpm-macros.git"
       dest: "pyproject-rpm-macros"

This is currently always cloned on the default branch (master).
How do I clone it on a different branch or switch to it? In particular, I need 
it to be the same branch we are on -- aka if the tests runs on a f32 Pull 
Request, the branch should be f32.

We currently keep rpms/pyproject-rpm-macros identical across braches, but if we 
ever stop doing that, I need the approprioate tests to be executed, not rawhide 
tests.

Thanks,
