compat: do not patch pydantic if the installed version starts with "1." (#3482)

Browse Source 
In pydantic 1.10.16 (hopefully the last version), they added the `pydantic.v1`
namespace to make transitioning to the v2 package easier without changing code.

However, Reflex was depending on pydantic v1 NOT having `pydantic.v1` to skip
patching names from `v1` into the top level `pydantic` (normally we do this to
force sqlmodel to use v1, even when the v2 package is installed).
