remove github update

[arita37]

hello,

it's very good and am fine to fund you if needed. But, what is needed: Make optional Github gist update (not secure). Better use cases.

Hey, thank you.

Make optional Github gist update (not secure).

This is already optional, right? Don't add any token, don't use push or pull command. You should be able to use keep locally without any github gist feature.
