(doc): Change error message to reference column that has mismatch

[Rizxcviii]

When receiving the following error during upserting (

iceberg-python/pyiceberg/io/pyarrow.py

Line 1971 in da88b8d

f"Unexpected physical type {physical_type_string} for {iceberg_type}, expected {expected_physical_type}"

), we are not sure of what column has the incorrect data type.

A possible error message to show which will be more descriptive is the following:
Unexpected physical type {physical_type_string} for {column_name} with iceberg type {iceberg_type}, expected {expected_physical_type}
