[FEAT]: enable repository code-quality setting (PREVIEW)

### Describe the need

Implements a call to the internal GitHub Enterprise endpoint
POST ///settings/code-quality to toggle the repository’s Code Quality feature.
This mirrors the GitHub UI action for enabling/disabling code scanning or quality checks (e.g., CodeQL), though it’s not part of the public REST API.

Details:

- Endpoint: /settings/code-quality (internal GHE)
- Request body: { "enabled": true }
- Effect: Activates repository-level code quality analysis
- Closest public equivalent: POST /repos/{owner}/{repo}/code-scanning/alerts
