feat: display `alignment` & `criteria` for Open Badges 3.0

[Oran-Dan]

Description of change

I've added the alignment field in Openbadge to the fields which are displayed in the Badge Overview.

The serde_json dependency updated from 1.0.20 to 1.0.28. This created a flaky error message being returned in the fn validate_domain_linkage (meaning it wasn't consistent between different runs and different environments). To counter this we have made static error messages which are more explicit.

For you next frontend PR, please add some hints for reviewers on how to test the UI changes. In this case I can't fire up my local UniCore because it does not have the credential config I need to test. I figured it out, but the easier you make it for me the faster I review :)

You're right, duely noted
