Upgrade Nextcloud, Redis, MariaDB, and Collabora to Latest Versions

[stephdl]

Request to update bundled software versions: Nextcloud v31, Redis v7.4.4, MariaDB v10.6.22, Collabora v25.

Upgrading these components will ensure improved security, performance, and compatibility with latest apps and integrations.

Proposed solution

Upgrade:

• Nextcloud to v31
• Redis to v7.4.4
• MariaDB to 10.6.22
• Collabora to v25

Alternative solutions

Continue using current versions and apply backports/patches as needed, but this may not provide all improvements and future compatibility.

Additional context

These upgrades align with upstream recommendations and user demand for up-to-date features.

target
collabora : ghcr.io/nethserver/collabora:1.0.11-dev.1
nextcloud: ghcr.io/nethserver/nextcloud:1.4.4-dev.1

Notes
After upgrade we still have the normal messages about some database fixing indexes

• one-or-more-mimetype-migrations-are-available
  runagent -m nextcloud1 podman exec -ti --user www-data nextcloud-app php ./occ maintenance:repair --include-expensive
• some-indices-are-missing-in-the-database
  runagent -m nextcloud1 podman exec -ti --user www-data nextcloud-app php ./occ db:add-missing-indices

QA

take care to read logs to see if the upgrade of version (redis, mysql but also nextcloud) does not create warnings/errors

• case 1 direct install
  install an account provider, then nextcloud and collabora (maybe you need a LE certificates) from testing

• case 2 upgrade
  install from STABLE an account provider, nextcloud and collabora (maybe you need a LE certificates), then upgrade nextcloud and collabora to testing

No expected issues, LDAP authentication, nextcloud and collabora must be workable together.
