[DOCS] Clean up more duplicated enum values

[lcawl]

Continues #4441

This PR removes the remainder of the cat -h or -s long lists of enum values from the OpenAPI document via overlay since that info is now listed (with additional details) in the description.

It also cleans up some other places where we'd listed the "valid values" in the description and thus the information was appearing twice.
