Pin `pydantic>=2.0.0`

Description

kedro-viz 8.0.0 migrated to pydantic v2, without keeping backwards-compatibility. This requirement is not listed in kedro-viz's dependencies, pydantic is only being installed as a transitive dependency of fastapi, which is pinned to >=0.100, but 0.100 is compatible with pydantic v1

I checked all utils.py files in kedro-viz and didn't see where this import is coming from 😅

@rashidakanchwala @ravi-kumar-pilla is there a way to turn this into a full traceback?

I see that kedro viz run doesn't have a --verbose flag of sorts. Should we open a different issue about this?

@astrojuanlu - We have the import in models -> flowchart.py . So the error is triggered due to import error

The --verbose option was previously asked by another user as well. I think Kedro supports this option and we can create a ticket to add support in viz too

Okay, here it is

https://github.com/kedro-org/kedro-viz/blob/2a6cff73b3ab19f74dc90b979255b212d669b389/package/kedro_viz/models/flowchart.py#L15-L19

This is another instance of #1821

In fact we're discussing about adding it, but it would mean a slightly different thing. Let's keep @iamelijahko in the loop before going ahead.
