I love this extension but the one thing I would get the most use out of would be to have it return just the name of the default branch so that it can be used in other scripts.

Example: gh default-branch show -name

Expected output: main

Currently: gh default-branch show

Output: Current default branch is "main"

In order to make use of this output additional work must be done to isolate only the name of the branch so that it can be used in terminal scripts.

If this could be added it would make my day! 🥰
