JSON Schema $ref parser library migration

[saulipurhonen]

Proposed solution

We're using https://github.com/APIDevTools/json-schema-ref-parser for dereferencing our schemas.
As for now we have multiple dependency update PR's waiting for updates and this library seems to be the culprit that we're not able to update these Dependabot PR's.

Conclusion for this can be read in #590 but the main thing is that react-scripts package has a dependency for Webpack 5 and schema parser library doesn't work out of the box with this.

Possible solutions:

• https://github.com/Eomm/json-schema-resolver
• https://github.com/hyperjump-io/json-schema-core
• https://github.com/saibotsivad/pointer-props
• Omit references recursively: https://stackoverflow.com/a/39090185/13164589

DoD (Definition of Done)

Dereferencing schemas do not rely on APIDevTools/json-schema-ref-parser library.

Testing

Current tests pass
