fix(ci): extract version number from PR title

The workflow was using the full PR title (e.g., 'Release 3.2.1') as the
version string, causing Docker tags and release creation to fail.

Now extracts just the version number (X.Y.Z or X.Y.Z-suffix) from the
PR title, handling formats like 'Release 3.2.1', 'v3.2.1', or '3.2.1'.
