Code review comment for ~alexmurray/ubuntu-security-tools:umt-check-warn-missing-cve-lp-bugs

I like Rodrigo's idea but there's several hundred entries in UCT with 'short' launchpad URLs:

± rg https://launchpad.net/bugs/1 | wc -l
803

It'd be nice to be a bit tighter than just 'launchpad'; 'launchpad.*bug' seems to work to catch cases like:

https://bugs.edge.launchpad.net/ubuntu/+source/lynx-cur/+bug/613254
https://bugs.launchpad.net/bugs/1570694
https://bugs.launchpad.net/qemu/+bug/1914353
https://bugs.launchpad.net/ubuntu/+source/mapserver/+bug/617489
https://launchpad.net/bugs/999359

Is adding regex here okay?

Thanks
