Rename crysostat fixture & rm whitespace in provider name

[jsm84]

Summary:

• The new HC-17-002 test was failing due to two reasons:
  1. The chart contained the redhat- prefix (partner submission)
  2. The provider name Red Hat was incorrect (should be RedHat)
• This fixes both issues with the cryostat chart itself. New reports will follow in a separate PR.
