optional ignore list for no-unresolved-refs rule

Is your feature request related to a problem? Please describe.

We use the lint command for OpenAPI descriptions throughout separate phases of the design lifecycle.

• during schema authoring
• bundling descriptions
• in our build

We've run into a scenario where we have certain schemas generated during the build which are documented during the design phase. The linter is flagging these references as unresolved, correctly.

Describe the solution you'd like

I'd like the ability to pass an array of patterns or strings to be matched to the ref uri string to ignore in this particular rule. I can't completely turn the rule off because we only use $ref in our descriptions. no in-line schemas are allowed except for very particular exceptions.

Something like no-http-verbs-in-paths optional validation would work great.

rules:
  no-unresolved-refs: 
    severity: warn
    ignored:
      - meta

Describe alternatives you've considered

I've considered duplicating the rule as a custom rule to insert this logic

Additional context

Start with the lint command and the no-unresolved-refs rule configuration. Trace how rule options are parsed and how $ref URI strings are checked; done means patterns such as meta can suppress matching unresolved references while other unresolved references still produce warnings.
