Provide Org and Repo name support in autolinks for dynamic pull request URI generation

[khaled-maruf]

Description

Autolinks now only has the <num> template that can be used for prefixes like JIRA- etc., but sometimes we may want to make the pull request links for #123 clickable as well. e.g. github.com/foo/bar-repo/pull/123, but as the URLs are dynamic it's not possible to have a global setting for this, only per repo.
If the Org name (owner) and repo name would be provided as templates then it'd be much easier to make these urls generic.

e.g.

  {
    "prefix": "#",
    "url": "https://github.com/<owner>/<repo>/pull/<num>",
    "title": "View Pull Request #<num>"
  }
