Add Support for Bypass privileges in Code Security Configurations

Feature Request: Add support for secret scanning delegated bypass fields

The CodeSecurityConfiguration struct in github/orgs_codesecurity_configurations.go is missing support for the following fields documented in the REST API:

• secret_scanning_delegated_bypass (string)
• secret_scanning_delegated_bypass_options (object containing reviewers array)

Related API Documentation:

• https://docs.github.com/en/enterprise-cloud@latest/rest/code-security/configurations?apiVersion=2022-11-28#update-a-code-security-configuration
• the enterprise variant does not list the field, but includes it in the response schema: https://docs.github.com/en/rest/code-security/configurations?apiVersion=2022-11-28#create-a-code-security-configuration-for-an-enterprise. The UI also supports it. I will try it out for our enterprise.

Use Case:
These fields are required to configure bypass privileges and bypass reviewers for secret scanning in code security configurations.

I will try to contribute this enhancement.

Amendment:

Enterprise Code Security Configurations do not support these fields as of now:

{
  "message": "Invalid request.\n\nInvalid input: \"secret_scanning_delegated_bypass\", \"secret_scanning_delegated_bypass_options\" are not permitted keys.",
  "documentation_url": "https://docs.github.com/rest/code-security/configurations#create-a-code-security-configuration-for-an-enterprise",
  "status": "422"
}

The UI uses a different API endpoint: https://github.com/enterprises/{ENTERPRISE}/settings/security_analysis/configurations/

I will have to investigate how my contribution can implement this only for organizations.
