Add ssh-agent usage example

[orevial]

Just added a small example of ssh-agent usage for Git push

[daniel-beck]

Is git-credentials the ID of these credentials? If so, should be made explicit (or show a UUID instead to be super clear it's an ID).

[orevial]

Yes it is the ID of the SSH credentials. What would you put as the credentials ID ? "git-ssh-UUID" ? Tell me and I'll change the code accordingly.

[daniel-beck]

Well, git-credentials-ID would be a solid improvement already. Change the previous use (credentialsId: MyID) accordingly for consistency and it should be clear enough IMO.

[orevial]

Hmm I'm not sure we want to use the same Id in both examples because it could be confusing to read twice the same Id for different use cases (username/password and SSH)

[orevial]

I've modified both credentialsId, I'll let you judge if that's fine for you.

@orevial Thank you!
