Feature Description

I propose adding a new configuration variable to the app.ini file in Gitea, allowing administrators to define a maximum limit on the number of users within a deployment. Similar to the MAX_CREATION_LIMIT feature for repository creation, this enhancement would provide greater control over the scalability and management of Gitea instances.

Additionally an option for Admins to update and change this configuration from the Admin UI could be a good idea. But this option should be enabled in api.ini file to do so.
