show github trigger ssh key signature

Presently when a new trigger is created, the ssh public key is shown to the user. I assume the idea behind that is to allow user to identify key in github once trigger is to be deleted and avoid confusion when other deploy keys in github are available.

But in github the keys are listed only with their SHA256 fingerprints.

So user has to save ssh key to a file locally. Then check it's signature:

ssh-keygen -l -f /tmp/key.pub

Only then is user able to identify which one is the matching key on github.

It will be user friendly to show the key signature along with the actual key to the user so comparison can much more easily be done.

btw is there any reason for quay not to remove the deploy key when trigger is removed? This would be even better.
