CLN GH22874 replace bare excepts in pandas/io/pytables.py
This PR changes bare excepts in `pandas/io/pytables.py` to more specific exceptions. I defaulted to using specific exceptions that seemed likely/triggered test errors, but it may be the case that I'm missing some or it's better to leave it as `Exception`.
