TIL: set up push mirroring from GitLab to GitHub

The GitLab free tier only allows free mirroring to GitHub, not pulls from GitHub. That requires the first paid tier. To set up your push mirroring follow these steps:

1. Go to your project on GitLab. Click Settings -> Repository.
2. Click to expand the Mirroring repositories section.
3. Enter your Git repository URL. If you’re on the free tier like I am, the Mirror direction option will be locked to push. Otherwise, pick push or pull as you’d like.
4. Choose an authentication method.
5. Click Mirror repository to set up the mirroring.

You should see in the Mirroring repositories section an entry for your GitHub repo such as https://****:*****@github.com/tydar/kvm-conjurer.git. You’ll see also Last update attempt and Last successful update columns, indicating when the push to GitHub from GitLab was last attempted and whether it succeeded. On a push mirror setup, GitLab should push your changes to GitHub as they come in.
