feat!: [torrust#537] move API healthcheck endpoint

From: `GET /health_check`
To:   `GET /api/health_check`

To avoid collission with HTTP Tracker health check enpoint when the API
and the HTTP Tracker are using the same domain+port. For example:

- API:          https://tracker.com:443/api/
- HTTP tracker: https://tracker.com:443/

Old health check endpoints:

- API:          https://tracker.com:443/health_check
- HTTP tracker: https://tracker.com:443/health_check

New API health check endpoint:

- API:          https://tracker.com:443/api/health_check
- HTTP tracker: https://tracker.com:443/health_check
