Remove runner flow: Change from PAT to "deletion token" in prompt (#225)

* Updating prompt deletion token

Currently if you leave the token off the command, we're showing "Enter your personal access token:"

Which won't work. This updates prompt to "deletion token"

* Call correct function in test

* Fix command text in test
