feat: Update to use Pydantic V2 and enable chunking

[mwiebe]

What was the problem/requirement? (What/Why)

The CLI depends on some implementation details of Pydantic V1 that have changed in V2. Need to update to match OpenJobDescription/openjd-model-for-python#164.

What was the solution? (How)

Modify the code to work with the Pydantic V2 openjd-model.

What is the impact of this change?

The CLI will continue to work after the Pydantic V2 upgrade

How was this change tested?

• Have you run the tests?

Yes

Was this change documented?

N/A

Is this a breaking change?

No, nothing about the CLI interface is changing.

This is an update to match a breaking change in the openjd-model library. That change is breaking because its interface is based on Pydantic, so code that depends on details that differ in V2 need to be updated.

Does this change impact security?

• Does the change need to be threat modeled? For example, does it create or modify files/directories that must only be readable by the process owner?
  • If so, then please label this pull request with the "security" label. We'll work with you to analyze the threats

No security impacts.

LGTM. Once the new model version is released we can update the PR.

I'd bias towards not a breaking change for this since it's an application that isn't changing as opposed to the library usage. But I won't die on that hill.
