The 3rd party ZIP component used by the ZIP Files action appears to have trouble with excluding double-extension filenames (i.e., *.fr.resx).
You could use the Copy Files action (which does support masks like that) to copy the desired files to a temp folder and then ZIP that folder without exclusions.
Another option would be to use the 7-Zip action.
