This pull request adds new functionality to convert JSON Schema strings to FormulaType objects and introduces comprehensive unit tests to validate this feature. The main focus is on enhancing the usability and robustness of schema-to-type conversion, ensuring support for a wide range of JSON Schema constructs and error scenarios.

New JSON Schema to FormulaType conversion:

• Added two new overloads to OpenApiExtensions for converting a JSON Schema string to a FormulaType, one with default settings and one allowing custom ConnectorSettings. These methods handle various schema types and error conditions.

Expanded unit test coverage:

• Introduced extensive unit tests in OpenApiExtensionTests to verify the new conversion methods, including:
  • Primitive and formatted string types (e.g., string, number, date-time)
  • Objects, nested objects, arrays of objects/primitives, and file types
  • Handling of unsupported types, invalid input, and exceptions
  • End-to-end test that parses a complex nested schema, deserializes JSON data, and evaluates a Power Fx expression using the generated type
• Added System.Text.Json import to support JSON parsing in tests.
