[Bug]: Nextcloud doesn't check system requirements for recommended apps

[iandk]

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

When installing a new instance of Nextcloud it recommends to install a few selected default apps.
However Collabora as well as Collabora CODE Server don't seem to work in Shared Hosting environments as they require special php modules and elevated access.

Unfortunately Nextcloud still allows the user to install those apps, even if the requirements aren't met.
This results in nextcloud locking up after installation and loading extremely slow.

Steps to reproduce

1. Install Nextcloud on Shared Hosting or on similar system which doesn't support Collabora
2. Enable the installation of the recommended default apps
3. Nextcloud will still try to install Collabora even tho the system doesn't meet the requirements
4. Nextcloud hangs after installation and all requests take extremely long5.

Expected behavior

Nextcloud should check the system requirements before attempting or even suggesting an app to be installed after the initial setup screen.

This is rather a feature request to check if requirements of recommended apps before attempting to install them

[joshtrichards]

Looks like we call isMarkedCompatible() rather than analze() (or similar more thorough path to check requirements).

We also have an issue where richdocumentscode comes in two apps variants depending on architecture. If we fix the requirements check we can include both app variants in the bundle list, and the one for the incorrect architecture will get nicely excluded automatically.
