Migrating from github to codeberg: existing readthedocs projects

Recently, I made the decision to migrate select projects of mine from github to codeberg.

Today I started migrating wwvbpy, which has an existing readthedocs configuration. In readthedocs "edit project" page, the "repository URL" field was greyed out and uneditable.

It took me a few minutes but I eventually realized that before I could set the project URL I had to clear the "connected repository" and save the settings.

After that, I was able to manually edit the URL and then manually configure the outgoing webhooks, so that pushes to codeberg would trigger doc builds.
