Pydantic 2.0 support

Is your feature request related to a problem? Please describe.
I need to install feast with Pydantic 2.0 support, but it's pinned to pydantic>=1,<2

Describe the solution you'd like
Update dependency to pydantic>=2

Pydantic v2 offers improved performance (2x-50x faster), which can contribute to the overall efficiency of Feast.

Updating Pydantic to version 2 will be a valuable enhancement to the feast, and I am willing to contribute to this update if needed. I look forward to hearing your thoughts on this proposal and am open to discussing it further.
