Bump fastapi so that pydantic v2 is supported

[IngerMathilde]

Description

Update fastapi so that pydantic v2 is supported.

Context

Currently our new projects want to be able to use pydantic v2 for performance reason. However, this conflicts with kedro-viz, as they depend on fastapi <0.1 which depends on pydantic v1. The frustrating thing that this is not a problem for kedro runs, just for visualizing with pythonic kedro-viz. I suppose we could use the react standalone application, but this seems quite an overhead.

Possible Implementation

A new version using the new fastapi which supports pydantic v2, (is annoying as you have to keep two versions alive, legacy and new application)

Possible Alternatives

Make the python version standalone? So that it does not try to implement a session? No clue how it would work exactly.

Checklist

• Python
