### Rationale for this change
Require Numpy 2.0 to support newer features, allow newer numpy API/ABI
### What changes are included in this PR?
- Numpy 2.0+ requirement
- Pandas 2.2.2+ requirement (first wheel compatible with numpy 2.0)
- Pyodide 0.27.1 usage (numpy 2.0 api)
### Are there any user-facing changes?
Yes, in contrast to pyarrow 25, after merging this PR pyarrow 26 can't be used with Numpy 1.x or pandas 2.0-2.2.1
