feat: Upgrade internal Pydantic use to v2. Thanks @KristinnVikar! (#779)

* initial changes for update to pydantic v2

* remove debug print

* Update pydantic to v2.1.0

* Fix OpenAPI model rebuilding

* Parameters.classes_by_name use str as key
Looking at tests shows me that str as key instead of ClassName is more expected?

* Update tests to reflect new error messages

* update poetry lock

* Misc fixes for pydantic validation
* Schema union ordering try Schema before Reference
* Support for boolean values in Schema.enum
* Missing default=None in SecurityScheme.security_scheme_in which is enforced by Pydantic V2
* Update Pydantic to V2.1.1

* Add missing type to union in build_enum_property

* chore: Clean up a couple of warnings

* chore: Allow future semver-compatible versions of Pydantic

* fix: Undo incomplete support for bool enums

* chore: Reformat
