fix(actions): helps forked repos work by default

[rspurgeon]

This PR removes the license check workflow which is not necessary for "dependent" (forked or template invoked) repos. In addition this removes an assumption for a repo level setting that is kong specific.

I moved the timeouts to #48 , the license check cannot be removed, would require an internal approved Jira ticket. Hence closing this.

@Tieske Core plugins are bundled in the Kong/kong repos now. Which plugins use the license checker action?
