refactor: Add support for retrieving triples in Markdown format

This commit adds a new endpoint to the SPARQLRestAPI class for retrieving triples in Markdown format. The new endpoint is accessible via a GET request and accepts the same parameters as the existing endpoints. The response will be formatted as Markdown, allowing users to easily view and analyze the triples. This feature enhances the flexibility and usability of the API.
