gl2gh GitHub CLI Extension

I am working for some time now on a migration project from plattforms like Azure DevOps, Bitbucket and GitLab to GitHub Enterprise. There are official GitHub CLI extensions for the migration from Azure DevOps (ado2gh) and Bitbucket (bbs2gh) to GitHub but unfortunately none for the migration from GitLab to GitHub.

For this case I created based on the GitHub Enterprise Importer (gei) CLI extension the unofficial gl2gh CLI extension. This extension is based on the same code as the other extensions. The code you can find here.
