Fix incorrect attribute documentation in Deployments API

What does this MR do and why?

This merge request fixes the documentation for status attribute in Deployments API.

The attribute is currently listed as not required, when in fact, the actual implementation shows that it is in fact required for the following two API resources:

• Create a deployment (implementation)
• Update a deployment (implementation)

Additionally, both resources includes created as one of the allowed values for that attribute, while the implementation does not:

• Allowed values for create a deployment: running, success, failed, canceled
• Allowed values for update a deployment: running, success, failed, canceled

Resolves #368116 (closed).
