create testing case to check links are not dead in user guide doc

Description

As https://hibernate.atlassian.net/browse/HHH-14260 demonstrated, as time goes on, more and more hyperlinks in user guide becomes dead ones. An automatic way to be notified of such dead links would be great. Seems we can achieve the goal as following:

  • extract external links in user guide

  • come up with a testing case to check each of them one by one to see whether 404 is returned
