Backport #20275
Currently when a Team has read access to a organization's non-private repository, their access(in the `access` table) won't be stored in the database. This cause issues for code that rely on read access being stored, like retrieving all users who have read permission to that repository(even though this is confusing as this doesn't include all registered users). So from now-on if we see that the repository is owned by a organization don't increase the `minMode` to write permission.
Resolves#20083
