Noref more permissive gnd uri handling

[karkraeg]

❤️ Thank you for your contribution!

Description

This PR aims at simplifying the process of adding a GND ID to a person in the creatibutors modal. Until now users could only paste the actual GND ID, not one of the GND URIs. When researching a GND URI the Website of the german national library looks like this:

So most people will just copy and paste this URI. When then saving or publishing the draft in RDM there will be a "Creators: No valid scheme recognized for identifier." error, which in our opinion is a major inconvenience.

This PR allows for pasting both http://d-nb.info/gnd/<id> and https://d-nb.info/gnd/<id> in addition to GND:<id>, gnd:<id> and <id>. The normalization step is the same as before.
