Support Pandas 3

[ehsantn]

Pandas 3 is released but can't be used with PyIceberg due to the "<3.0.0" version restriction of PyIceberg. We need to update PyIceberg if necessary and remove the version restriction.

Thanks for raising this @ehsantn! Feel free to open a PR to remove the restriction if you like
