Outdated pydantic requirement in pyproject.toml

[yuema137]

The current rframe seems to use pydantic > 2.0.0, for example, BaseModel is only available in > 2.0.0

rframe/rframe/schema.py

Line 7 in 06af8ef

from pydantic import BaseModel, ValidationError, validate_model

But the requirement in pyproject.toml is > 1.9.0:

rframe/pyproject.toml

Line 24 in 06af8ef

pydantic = "^1.9.0"

As the requirement is not consistent, we should update accordingly. Otherwise, there will be some conflicts for other packages depending on Pydantic:
rframe 0.2.20 requires pydantic<2.0.0,>=1.9.0, but you have pydantic 2.6.4 which is incompatible.
