[Feature]: Detect if package suggested by `dependabot` is available in Fedora

[sarroutbi]

In order to keep upstream code aligned with Fedora, the process to merge new dependencies included by dependabot requires to check if the new process is packaged in Fedora Rawhide.

It would be nice to have a GH CI action that verifies it automatically (and exclusively on these kind of changes), so that it must not be checked, manually, if the updated version exists.
