[Suggestion] Adding more useful apps and upgrading NextCloud to newer version

I know this is not the correct repo for this issue but I couldn't open an issue in https://gitlab.e.foundation/e/infra/ecloud/nextcloud.

Consider upgrading to a more recent version of Nextcloud. I have noticed that Ecloud uses version 21 and it is end of life (https://scan.nextcloud.com/results/e5c5cea2-4678-418c-b312-8c9080c87db6). I (being a computer science student) also know that changing to a major version is not an easy task, but the latest versions have lot of security patches and performance improvements. So, Please consider upgrading to a later version. I have also noticed work is being done to upgrade to version 22. So kudos. Also consider changing the default mail app Rainloop to Nextcloud Mail (https://apps.nextcloud.com/apps/mail). Add Nextcloud Maps (https://apps.nextcloud.com/apps/maps), Music (https://apps.nextcloud.com/apps/music), Recognize (https://apps.nextcloud.com/apps/recognize) and External Sites (https://apps.nextcloud.com/apps/external). It would be nice if SearxNG (https://github.com/searxng/searxng) is integrated into the Ecloud ecosystem as it is much more powerfull than traditional search engines.
