docs(openapi): drop redeploy_requires_name from DeployRequest description

That error code was emitted by an unreachable defence-in-depth arm that
landed in api#201 and was removed before merge (requireName already
rejects empty/whitespace name upstream of the redeploy branch). The
DeployRequest description still mentioned it; tidied + clarified the
upstream-rejection path.
