Support for pydantic v2

[max-radin]

Describe the feature you'd like
Support for at least one 2.X.X version of pydantic.

How would this feature be used? Please describe.
Adding support for pydantic v2 would allow us to upgrade orquestra-sdk to also use pydantic v2 and benefit from the improvements it offers.

The reason for this is that the orquestra-core metapackage depends on pydantic transitively through orquestra-sdk as well as amazon-braket-default-simulator and amazon-braket-schemas-python. So currently, upgrading orquestra-sdk to pydantic v2 would create a dependency conflict for orquestra-core.

Describe alternatives you've considered
Our current strategy is to continue using pydantic < 2.0.0.

Hi @max-radin - thanks for raising this, we're looking at a couple of options before getting back.

Closing this issue as it is a duplicate of amazon-braket/amazon-braket-schemas-python#161
