Revoke my push access

[pykong]

@MiroHibler

Thanks again for putting up this nice little package and granting me push access to it.
I have given the package some love in the form of fixes:

• dropping ST2 support
• made flake8 happy
• some basic CI via GitHub Actions
• the formatted whole codebase
• tidied up the README
• switching to a tag-based release on packagecontrol see

I have also implemented rendering the cheat sheet as MarkDown which is great for exporting your keymaps and having them beautifully rendered. Maybe even to print them out and stick them somewhere next to your desk. #23 #27

I, however, do not want to further maintain the package, as I like to focus on other things.
Could you, therefore, please revoke my push access? (I seem I can not do it myself.)
