Validator Checks do Not Support Certain $refs

[BrodBlox09]

Describe the bug
The test/src/validator.test.ts file does not support $refs where both a relative path and a JSON pointer (e.g. "./path/to/json.json#/definitions/some-definition") are used.

To Reproduce
Steps to reproduce the behavior:

1. Fork this repository
2. Make some commit involving a "$ref" property with both a relative file path and a JSON pointer in use to a JSON schema
3. create a PR
4. See error after validator checks fail

Expected behavior
Checks should pass.

Additional context
Found after trying to submit a PR with a few $refs that fit this description.
