[I] [Python] the type of ParquetLogicalType not correctly returned for Geometry/Geography [arrow]

jorisvandenbossche opened a new issue, #50849:
URL: https://github.com/apache/arrow/issues/50849

   ### Describe the bug, including details regarding any error messages, version, and platform.
   
   When accessing the `.type` of the logical type of a Parquet schema for the new Geometry/Geography types, this still returns UNKNOWN instead of the correct type:
   
   ```
   >>> meta = pq.read_metadata("./cpp/submodules/parquet-testing/data/geospatial/crs-default.parquet")
   >>> meta.schema.column(1)
   <ParquetColumnSchema>
     name: geometry
     path: geometry
     max_definition_level: 1
     max_repetition_level: 0
     physical_type: BYTE_ARRAY
     logical_type: Geometry(crs=)
     converted_type (legacy): NONE
   >>> meta.schema.column(1).logical_type
   <pyarrow._parquet.ParquetLogicalType object at 0x7fc53c3f2cd0>
     Geometry(crs=)
   >>> meta.schema.column(1).logical_type.type
   'UNKNOWN'
   ```
   
   ### Component(s)
