Pull request overview
This pull request adds support for wildcard HTTP status codes (e.g., 2XX, 4XX, 5XX) in OpenAPI specifications, enabling the fetch client generator to correctly map these wildcard patterns to TypeScript types like HTTPStatusCode2xx, HTTPStatusCode4xx, etc.
- Implements regex-based detection and transformation of wildcard status codes to TypeScript type names
- Updates header generation logic to include HTTP status code types when wildcard codes are used
- Adds comprehensive test specification covering various wildcard and mixed response scenarios

This pull request adds support for handling wildcard HTTP status codes (like
'2XX','4XX', etc.) in the fetch client code generator. The changes ensure that wildcard status codes in OpenAPI specifications are correctly mapped to TypeScript types, and updates are made to both the code generation logic and the test suite to verify this behavior.This should resolve #950
