Feature Request: Check if nextcloud update is available

[BornToBeRoot]

Something similar to the app update... To see if a new nextcloud version is available...

There should be an info for major releases and for the current branch.

Example:

<data>
  <nextcloud>
    <update>
     <currentbranch_available>True|False</currentbranch_available>
     <currentbranch_version>V x.x.x.x|none</currentbranch_version>
     <major_available>True|False</major_available>
     <major_version>V x.x.x.x|none</major_version>
   </update>
  </nextcloud>
</data>
