For AWS CCS clusters - Use the new endpoint /api/clusters_mgmt/v1/aws_inquiries/regions to fetch regions filtered by OCP versions.

We have to pass the cluster's version in order to get the filtered regions.

This one follows up on https://issues.redhat.com/browse/SDA-6667.

Acceptance Criteria

• UI should hide (or disable) region ap-southeast-3 regions  when cluster versions older than 4.10 is selected
  (EDIT: or is it 4.11?  seems backend is filtering it out for 4.10.x as well)
  see: https://issues.redhat.com/browse/HAC-448
• For CCS AWS clusters: OSD & ROSA classic & ROSA hypershift
  [EDITED: -GCP- is out of scope, no filtering in backend yet]
• regions dropdown on Cluster details step should be filtered by selected cluster version
• If user changers credentials or cluster version, UI must invalidate the regions response to trigger refetch with new credentials and/or cluster version.
