Fix issue URL in job log

[fnkr]

GetURL returns the API URL of the issue, e.g.:

Issue created: https://api.github.com/repos/user/repo/issues/123456

It would be more useful to put the HTML URL (for human use) in the job log:

Issue created: https://github.com/user/repo/issues/123456

API docs: https://docs.github.com/en/rest/issues/issues?apiVersion=2022-11-28#get-an-issue

{
  // ...
  "url": "https://api.github.com/repos/octocat/Hello-World/issues/1347",
  // ...
  "html_url": "https://github.com/octocat/Hello-World/issues/1347",
  // ...
}

There's a similar issue with the link to the run created in the Issue body. runURL() is generating an API url instead of one for human use.
