Old GCParser logic inserted an HTML link to their geochecker (when applicable)
directly into the description text.
When running on Android 12 this direct URL might be redirected to c:geo under
specific system settings, leading to a loop (see #12889), so let's reassign
this link to the proper openGeochecker method.
