[v0/v1 migration] Remove all trailing instances of sparql

[juliawu]

Removes all remaining instances of the (v0) /sparql API from this repository.

As far as I can tell, the actual usage of /sparql and dc.query() which wrapped /sparql have already been removed. This PR just adds some final cleanup to remove trailing references to it.

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request finalizes the migration away from the deprecated v0 /sparql API. It systematically removes all remaining code, configuration, and documentation references to the old SPARQL endpoint, ensuring a complete cleanup of the codebase after its functionality was previously replaced.

Highlights

• API Deprecation Cleanup: Removed the query function from server/services/datacommons.py, which previously handled /v2/sparql requests.
• Endpoint Configuration Update: Deprecated the /v2/sparql endpoint by removing it from the list of known service URLs in server/services/discovery.py.
• Test Case Refinement: Updated test cases in server/tests/services/discovery_test.py to reflect the removal of the /v2/sparql endpoint.
• Ingress Configuration Cleanup: Cleaned up ingress configuration files (server/tests/test_data/ingress/test1.yaml and server/tests/test_data/ingress/test2.yaml) by removing mappings for /v2/sparql.
• Documentation and Comments Update: Updated documentation and comments in tools/sitemap/README.md and tools/sitemap/main.py to remove references to the old SPARQL API.
