feat: ProblemDetails 2020-12 JSON Schema definition

[sim13pods]

In the company we love to define our APIs errors according to the RFC9457 and then re-defined a reusable schema, starting from your initial version included in the README, which refers to the updated 2020-12 specification and that is used to:

• be linked in OpenAPI documentations;
• automatically generate Python models;
• So we think it would be a good idea to contribute it back in order to alleviate the problems-registry users the task to write boilerplate code.

Having it in the repo as a proper file, rather than in the README, would also alleviate the task to users to import it in their projects , while it can be linked even from the GitHub RAW service, i.e. https://raw.githubusercontent.com/sim13pods/problems-registry/refs/heads/main/schema.yaml

We tested it already with

• datamodel-code-generator
• json-schema-for-humans
• Redocly CLI commands

Any feedback about eventual follow-up, in order to match your requirements, will be very appreciated.

Please have a look at the updated version of the OpenAPI definition, re-defined starting from https://app.swaggerhub.com/domains/smartbear-public/ProblemDetails/1.0.0

We found very useful defining types in order to generate Python's Pydantic v2 models then adopters just have to instantiate errors instances, without manually setting the URL type
