[Dumpert] Broader url support

[rvsit]

IMPORTANT: PRs without the template will be CLOSED

Description of your pull request and other information

Now supports any url with ?selectedId= such as https://www.dumpert.nl/toppers/dag?selectedId=100086074_f5cef3ac

(Did not make issue because seem a fairly straightforward fix).
All tests run, see https://regex101.com/r/sXNP7f/1 to confirm that the regex still works properly for the other urls.
