Add permission to create Gitea repositories from the command line

[bganslandt]

To create Gitea repositories from the command line must currently be done via the Gitea web interface when logged in as a gitea user, making it hard to automate app builds. This is due to a missing permission for user level push to create repos.

Please add the following line to the gitea-inline-config secret in the cp4ba-collateral namespace:

ENABLE_PUSH_CREATE_USER=true
