Support for GitHub Advanced Security and Secret Scanning.

The current repository resource does not support the parameter: security_and_analysis which is used to enable both GHAS and secret scanning on a repository:

Specify which security and analysis features to enable or disable. For example, to enable GitHub Advanced Security, use this data in the body of the PATCH request: {"security_and_analysis": {"advanced_security": {"status": "enabled"}}}. If you have admin permissions for a private repository covered by an Advanced Security license, you can check which security and analysis features are currently enabled by using a GET /repos/{owner}/{repo} request.

This parameter is already supported in the go library with google/go-github#2132 .
