Restore Molecule verification and add AlmaLinux 10

[viru0909-dev]

Fixes #518

Description

This PR restores the Molecule verification logic and RPM install workflows from PR #536, which were previously reverted.

Key Changes:

1. Restored Molecule Config: Reintegrated the molecule configuration and RPM install workflows.
2. Fixed Regression: Crucially, I have excluded the changes to the Jenkinsfile from the original PR Stabilize Molecule verification and RPM install workflow #536. The Jenkinsfile remains identical to upstream/master to avoid the previous build failures.
3. Added AlmaLinux 10: Updated molecule/default/molecule.yml to include almalinux-10 in the test matrix (using the dokken/almalinux-10 image), satisfying the request in issue Test on AlmaLinux 10 #518.

Testing done

• Verified that the Jenkinsfile is unchanged to ensure stability.
• Updated molecule.yml to include the new platform.
• Relying on CI/Molecule execution to verify the new AlmaLinux 10 container instantiation.
