The custom regex manager matched all nextcloud_image entries with the
same depName, causing Renovate to bump all matrix entries (NC 31, 32, 33)
to the latest version instead of only the targeted major.
Fix by capturing nextcloud_version to create version-specific dep names
(nextcloud-31, nextcloud-32, nextcloud-33) with allowedVersions rules
constraining each to its own major. Also pins docker-compose.yml to 32.x
and removes redundant inline # renovate: comments that could cause
duplicate matching.
