Fixes
- Update [E3031](https://github.com/aws-cloudformation/cfn-python-lint/blob/main/docs/rules.md#E3031) so all regex checks are run (pull [2873](https://github.com/aws-cloudformation/cfn-lint/pull/2873))
- Update [E2520](https://github.com/aws-cloudformation/cfn-python-lint/blob/main/docs/rules.md#E2520) to better skip properties we don't care about (pull [2875](https://github.com/aws-cloudformation/cfn-lint/pull/2875))
