Please remove regex for ghp_ token

[vandlol]

This change just broke the playbook for me.
My perfectly alright token is no longer working.
Also, if you need to check for a token prefix (which seems odd to me) please check for all of the prefixes:
ghp for GitHub personal access tokens
gho for OAuth access tokens
ghu for GitHub user-to-server tokens
ghs for GitHub server-to-server tokens
ghr for refresh tokens
I am using your Playbook on a Github Enterprise Server which does not need any prefixes for tokens.
Please make this optional or something.
