GitHub CLI extensions are repositories that provide additional gh commands.
The name of the extension repository must start with "gh-" and it must contain an
executable of the same name. All arguments passed to the
gh <extname> invocation
will be forwarded to the
gh-<extname> executable of the extension.
An extension cannot override any of the core gh commands.
