Added support for `FileStreamResult`, `FileContentHttpResult`, and `FileStreamHttpResult` in `OpenApiSchemaService`. These types are now represented as binary string schemas in OpenAPI documentation. Updated `JsonTypeInfoExtensionsTests` to include test cases for the new types, ensuring proper handling and naming in the schema. Added new test cases in `OpenApiSchemaServiceTests` to verify OpenAPI response handling for the new HTTP result types, validating schema generation with appropriate content types. These changes improve compatibility with new ASP.NET Core features and enhance the accuracy of API documentation.

Pull request overview
This PR adds support for three new HTTP file result types (FileStreamResult, FileContentHttpResult, and FileStreamHttpResult) to the OpenAPI schema generation service. These types join the existing FileContentResult in being represented as binary string schemas in OpenAPI documentation, improving compatibility with recent ASP.NET Core features.
Key Changes
- Extended
OpenApiSchemaServiceto recognize and handle the new file result types as binary string schemas - Added test data entries for the new types in
JsonTypeInfoExtensionsTeststo verify proper schema reference ID generation - Created comprehensive test cases in
OpenApiSchemaServiceTeststo validate OpenAPI response handling for each new type
