[Documentation Update] opendistro_security_roles is supported for opendistro-1.3.0+ versions

What is the bug?
Confusing documentation around opendistro_security_roles field while creating Internal users via API, which provide respective permissions to the user without explicit roles mapping.

Note that any role you supply in the opendistro_security_roles array must already exist for the Security plugin to map the user to that role. To see predefined roles, refer to the list of predefined roles. For instructions on how to create a role, refer to creating a role.

But opendistro_security_roles support was added for ES-7.3+ version commit.

What is the expected behavior?
Documentation should be updated saying opendistro_security_roles is supported from opendistro-1.3.0+ versions.

What is your host/environment?

Start at the linked Create User API documentation and review its note alongside the linked predefined-roles and create-role sections. Update the note to state that opendistro_security_roles is supported for opendistro-1.3.0+ versions, then verify the wording and links in the rendered documentation.
