feat: update to latest json schema test suite

[DannyvdSluijs]

This pull request updates the json-schema/json-schema-test-suite dependency to a newer version and introduces a new test suite for validating JSON schemas. The goal here is to have a quicker turnaround then just the bowtie reports. The most important changes are grouped below:

Dependency Updates:

• Updated json-schema/json-schema-test-suite dependency in composer.json from version 1.2.0 to ^23.2 and updated the package version and reference in the repositories section to match the new version. [1] [2]

New Test Suite:

• Added a new JsonSchemaTestSuite class in tests/JsonSchemaTestSuite.php to run validation tests using the json-schema/json-schema-test-suite. This includes:
  • A testIt method to validate test cases and assert results.
  • A casesDataProvider method to dynamically load test cases from the json-schema-test-suite repository, skipping certain drafts.
  • A loadRemotesIntoStorage helper method to load remote schemas into the schema storage.
