MinIO Server RELEASE.2024-01-01T16-36-33Z has changes that impact the docs:

• New set of WebUI envvars to address security concerns PR #18631
• Check and finish cleanups for RoleARN -> RoleArn PR #18711
  This was partially addressed in Fix the name of RoleArn param in AssumeRoleWithWebIdentity requests #1095, but a few more need to be fixed.
