docs: align documentation style with codebase conventions

- Use "This resource allows you to..." voice (matches all enterprise resources)
- Use "Creates and manages" in frontmatter description
- Move admin access note to inline text (matches enterprise_actions_permissions)
- Add empty "Attributes Reference" section (matches enterprise_security_analysis_settings)
- Remove ~> callout for destroy note (no precedent in enterprise resource docs)
