Extend apps in admin-settings by version compatibility info #3412

Initial Checklist

• I understand this is a user story and questions should be posted in the Community Discussions
• I searched issues and couldn’t find anything (or linked relevant results below)

User Story

As an admin, I want to see compatibility info of my installed apps so that I have an easier time debugging when one app doesn't work.

User Value

UX/DX (for admins)

Acceptance Criteria

• https://github.com/opencloud-eu/awesome-apps/blob/main/webApps/apps.json gets extended by maxOpenCloud for app versions that have it (might only be some of them)
• The apps list in the admin settings fetches https://github.com/opencloud-eu/awesome-apps/blob/main/webApps/apps.json and gets extended by 2 new cols for min and max OpenCloud versions
• If an installed app doesn't support the current OC version, the status column should be red. a contextual helper should provide the info that the version constraint is not fulfilled.
• If the request to https://github.com/opencloud-eu/awesome-apps/blob/main/webApps/apps.json fails for some reason (missing CSP rules, most likely), notify the admin about it on this page (error message, info text, ...?)
