GH-48759: [Python] Remove skip condition for pandas/issues/50127 (#48760)
### Rationale for this change
Tests `test_binary_column_name` and `test_roundtrip_with_bytes_unicode`
were being skipped on pandas 2.0+ due to a pandas regression
(https://github.com/pandas-dev/pandas/issues/50127) that caused
`NotImplementedError: |S3` when roundtripping DataFrames with bytes column
names.
This issue was already fixed in commit e2ac52d661d (GH-44171) by changing
an `if` statement to `elif` in `_reconstruct_columns_from_metadata()`. The fix
prevents bytes-typed columns from falling through to the `level.astype(dtype)`
call that triggered the pandas error.
### What changes are included in this PR?
Remove the skip conditions from two test cases.
### Are these changes tested?
Yes all related tests pass.
### Are there any user-facing changes?
No.
