BUG: Raise error when filtering HDF5 with tz-aware index (GH#61479)
This PR addresses a bug where applying a .select(where=...) query on an HDF5 store with a timezone-aware DatetimeIndex raised a confusing or incorrect error. Since tz-aware filtering isn't currently supported, we now raise a clear ValueError when such filtering is attempted.
What’s included:

-Adds a specific check in select() to detect and error on tz-aware index queries

-Includes a minimal test case reproducing the issue in test_timezone_bug.py

Closes: #61479
@AnushaUKumar - the linked issue is not about timezones, did you perhaps get the number wrong? Thanks for the pull request, but it appears to have gone stale. If interested in continuing, please merge in the main branch, address any review comments and/or failing tests, and we can reopen.
