Auto-connect for budgie-common-themes and linux-mint-themes snaps

As per the details from Process for aliases, auto-connections and tracks under “content for theme snaps”, these snaps are:

  • appear to contain only (valid) content files
  • does not ship any commands, daemon or hooks

@Desire_Kyuyrii - are you a member of the budgie or mint upstreams? Just looking to get a better idea of assurance from the snap publisher that they will maintain a stable “API” for the content interface and hence won’t remove things from it etc which could then break other snaps which use the content interface. Similar to the comment in this thread
