Feature Request - Settable details link

[ezelkow1]

I think it would be good if we could also pass down text for the 'details' link in github statuses via setGitHubPullRequestStatus, just as an optional item

Our use case is that we have a top level pipeline being triggered that then manages a variety of tests and builds and such. So I have a function setup that runs each one of those and on completion does setGitHubPullRequestStatus for each step. However the details links is automatically populated with the URL of the top level pipeline. I can get the individual run's pipeline via absoluteURL, but there's no way to change the one that details refers to
