Add option to support override-ready paths in Spectral diagnotsics

[DavidBiesack]

User story.

As a Spectral user, I can use a command line option so that the locations in Spectral's error/warning/information diagnostics use the same notation/syntax as the overrides/files notation in a Spectral ruleset.

Is your feature request related to a problem?

It is tedious and error prone to manually specify the files locations in ruleset overrides.
The diagnostics emitted by Spectral use one format that differs from that used in a ruleset.

I.e. for the Redocly Museum sample OpenAPI
and the oas and Spectral OWASP ruleset, Spectral emits many diagnostics, such as

 108:17  warning  owasp:api4:2023-rate-limit-responses-429    Operation is missing rate limiting response in responses[429].                                      paths./special-events/{eventId}.get.responses

If one wanted to add an override for a specific instance (not just disable the entire rule), one must "map" the path notation paths./special-events/{eventId}.get.responses to

overrides:
  files:
    - 'test/data/openapi.yaml#/paths/~1special-events~1%7BeventId%7D/get/responses'

Describe the solution you'd like

Add a command line option so that the Spectral output uses the notation required for the ruleset overrides
Such as

 108:17  warning  owasp:api4:2023-rate-limit-responses-429    Operation is missing rate limiting response in responses[429]. test/data/openapi.yaml#/paths/~1special-events~1%7BeventId%7D/get/responses

Additional context

Note that the new location should use the relative file location, not the absolute file location that Spectral emits when processing a file, since ruleset files normally use relative files file paths (i.e. relative to the current directory when running the spectral CLI)

Another option is to add a json-pointer or similar property to each item in the output when using --format json.
I don't know which other output formats are extensible - I don't what most of the output formats

["json", "stylish", "junit", "html", "text", "teamcity", "pretty", "github-actions", "sarif", "markdown","gitlab"]

mean, so only adding to JSON will meet the need without getting too complex.

I tried to work on a PR to address this in packages/formatters/src/json.ts but when I clone the repo, yarn && yarn build yielded errors and the CONTRIBUTING guide does not make it clear how to add a dependency (the formatters uses package.json -- so how/where do I add a dependency to the json-pointer package?
