Remove Pydantic limitation for version < 2 (#33507)

We already fixed all deprecation warnings for Pydantic 2 and we can
thus remove Pydantic 2 limitation. Even if we are waiting for other
dependencies (aws-sam-translator) it should be save to remove the
limit - we will get Pydantic 2 when aws-sam-translate new version
is released in a week or two (Pydantic 2 support has been added
last week in
aws/serverless-application-model#3282)
