feat: problem details plugin

[peterschutt]

Description

A plugin to enable usage of problem details as the response.

The way this works is by injecting an exception handler into the app level exception handlers to convert ProblemDetailsException into a response following the specification as per RFC 9457.

Users can pass in a mapping of exception types to callables that will convert those exception types into ProblemDetailsException for handling specific exceptions such as pydantic's ValidationError. That converted ProblemDetailsException will then be used to create the response. This should allow for flexibility when needed.

Closes

Closes #3199.

At risk of stating the obvious, it looks like its waiting on some comments to be resolved and a rebase.

This is tagged for 2.9.0 but 2.9.0 was just released. I think the milestone needs to be updated.

[bunny-therapist]

This is tagged for v2.10.0 but it just came out and it did not contain this at all.

dang.. sorry about this @bunny-therapist - yeah it needed to be merged to be included - perhaps @Alc-Alc had a reason for not merging ready PRs before?
