"Physical input schema should be the same as the one converted from logical input schema." error does not display metadata differences #19069

Describe the bug

When logical and physical schema metadata mismatch, the error message does not show the metadata differences.

Example:

Error while planning query: Internal error: Physical input schema should be the same as the one converted from logical input schema. Differences: .

The Differences: . is confusing because it does not show any differences.

To Reproduce

Execute a query on a parquet file with metadata and skip_metadata = false where the physical/logical metadata do not match.

Examples of issues with reproducers:
#19049
#18337
