Ability to omit uid query in Forgejo autodiscover

[EnbyAce]

Tell us more.

I have my own Forgejo instance with a renovate admin user, so it is able to write to write to repositories which it doesn't own nor is in its contributors list. Renovate automatically adds a uid query with the bot's user ID as value. That's usually a good idea, but for Forgejo it hides all repositories the user, even if admin, doesn't own nor is in its contributors list.
