Pin DimensionalData to exclude v0.29.25

DimensionalData v0.29.25 (released Nov 6, 2025) introduced a CondaPkg.toml
that requires Python 3.13, which conflicts with ArviZ 0.18's requirement
for Python 3.10-3.12. This caused DimensionalDataPythonCallExt to fail
precompilation when both packages' CondaPkg requirements couldn't be
simultaneously satisfied.

The fix in DimensionalData (PR #1135) was merged on Nov 11, 2025 to move
CondaPkg.toml to test/, but hasn't been released yet. This pins
DimensionalData to 0.29.0-0.29.24 to exclude the problematic version.

Fixes daily CI failures that started on Nov 7, 2025.
