The link for the SR Core Registry REST API in the RH console Learning Resources and on the SR docs Splash page is:

• https://www.apicur.io/registry/docs/apicurio-registry/2.1.x/assets-attachments/registry-rest-api.htm

This should be:

• https://www.apicur.io/registry/docs/apicurio-registry/2.2.x/assets-attachments/registry-rest-api.htm

Fix these links as follows:

• Learning resources:
  Submit an upstream PR to update the following file:
  https://github.com/redhat-developer/app-services-guides/blob/main/.build/external-documentation/sr-core-api-reference.quickstart.yml
• Splash page:
  Edit the link using the Splash Page Manager in Pv1
• Upstream docs:
  Change https://www.apicur.io/registry/docs/apicurio-registry/2.1.x/assets-attachments/registry-rest-api.htm to point to 2.1.x and not 2.2.x
