Python: updated pydantic 2.10.3 works again

[eavanvalkenburg]

Motivation and Context

Manual update to pydantic requirement, they fixed the incompatibility in 10.3 (10.<3 was broken).

We need one more fix in Pydantic 2.10, which should come in 2.10.4: pydantic/pydantic#10910
this is the issue: pydantic/pydantic#11024
Comes into play with some of the vector stores.

So excluded 2.10 smaller then 2.10.4.

Closes #9788
