fix(scanner): exclude Vorbis VERSION from albumversion tag mapping (#5194)

The Vorbis/FLAC VERSION field is for track-level disambiguation (e.g.
remix, live, 30s edit), not album versioning. Including it in the
albumversion aliases caused albums to split incorrectly when tracks
had different VERSION values and no MusicBrainz Album ID was set.

Remove 'version' from the albumversion aliases in mappings.yaml.
Users who want the old behavior can re-add it via Tags config.

Update the PID test to use 'albumversion' directly instead of
'version' as the raw PID attribute, with a realistic value.

Fixes #5082
