refactor(general): drop pydantic v1

[leandrodamascena]

Issue number: #4191

Summary

Changes

This pull request removes support for Pydantic v1 in Powertools for AWS Lambda (Python) v3. Pydantic v2 will be the only supported version going forward.

Our codebase and test suite currently have many conditional checks to ensure compatibility with both Pydantic v1 and v2. This makes the codebase more complex and harder to maintain. By removing support for Pydantic v1, we can simplify the codebase and focus on providing the best experience for Pydantic v2 users.

Customers using Powertools for AWS Lambda (Python) v2 will not need to update their codebase, as those versions will continue to support Pydantic v1. However, customers upgrading to v3 will need to ensure that their codebase uses Pydantic v2. This may require updating their dependencies and making any necessary changes to their code to be compatible with the Pydantic v2 API.

Hey @heitorlessa, this PR is ready to review! We may need to discuss about this: https://github.com/aws-powertools/powertools-lambda-python/pull/4305/files#diff-50c86b7ed8ac2cf95bd48334961bf0530cdc77b5a56f852c5c61b89d735fd711R99.

I can't see any Pydantic deprecation warning in the tests, but please double check this.

superb work (I know how exhaustive this is) -- left one question about Bedrock Agents OpenAPI version workaround, and one ask to reduce memory usage for model_config = {"extra": "allow"} (define once).

[heitorlessa]

Random question, do you know the reason why we have this?

powertools-lambda-python/aws_lambda_powertools/event_handler/openapi/encoders.py

Line 321 in 17b62b8

Color: str,

It's the only place where we'd need this extra dependency.
