Surely it doesn't matter though because no one will be able to access anything using those keys without the private keys anyway...
I know, they are public, but I don't want to share information about a number of my keys, what exactly keys I do use to push my source code to github and other related things.
Why does it matter? Are your fears based on reason or just an uneasy feeling you have about publicizing data that you don't need to?
I'm not sure what you mean. Pushing code to a repo requires your private key.
