Support for pydantic2

[bohndthi]

Since Pydantic V2 has been finally released (https://docs.pydantic.dev/2.0/blog/pydantic-v2-final/) it would be great to add support for it.

fastapi-code-generator uses datamodel-code-generator to generate pydantic models. New version of datamodel-codegen already have support for pydantic v2, so I guess #379 should fix the issue.

@n0nvme you are right, but this package uses the fixed version of datamodel

datamodel-code-generator =  {extras = ["http"], version = "0.16.1"}

[serjflint]

V2 was introduced in v0.21.0

Any plans for this..?

I cannot use fastapi 0.103.0 with latest pydantic-settings from extras with your project because of this limitation.

fastapi (0.103.0) depends on pydantic-settings (>=2.0.0), fastapi (0.103.0) requires pydantic (>=2.0b3).
And because fastapi-code-generator (0.4.4) depends on pydantic (>=1.5.1,<2.0.0)

Are there any plans to prioritize this soon?
