Choose the content type of a GeoParquet download

[robinskil]

Problem

A GeoParquet download reports the content type of plain Parquet:

application/vnd.apache.parquet

See beacon-db/beacon-core/src/query_result.rs:53. The Parquet arm and the GeoParquet arm return the same value.

The test expects application/vnd.apache.arrow.geo+parquet.

One of the two values is wrong. Choose the correct one.

Failed test

• test_spatial.py::test_geoparquet_output_and_readback

Task

1. Choose the content type for a GeoParquet download.
2. Align the code and the test with that choice.
3. Run the file again.

Environment

Branch features/reimplement-atlas. Image beacon-integration:local.
