Let httpx transport errors fall through to caller

[kewisch]

Fixes #261

I needed to add pytest to optional depdendencies since flake8-requirements will prefer PEP621 over poetry's groups and apparently PEP 735 is not yet supported. I get I900 'pytest' not listed as a requirement otherwise.

https://github.com/arkq/flake8-requirements/blob/30242fe4b86730b69816e2d4e0ac2b74894b6381/src/flake8_requirements/checker.py#L743

Please see open question in #261 but I wanted to get this off my chest in case this is your preferred solution

Pull Request Overview

This PR fixes issue #261 by modifying the HTTPXEndpoint to let httpx transport errors propagate to the caller instead of being caught and handled internally. The change narrows the exception handling from httpx.HTTPError to httpx.HTTPStatusError, allowing transport-level errors like RemoteProtocolError to bubble up.

Key changes:

• Modified exception handling in HTTPXEndpoint to catch only httpx.HTTPStatusError instead of the broader httpx.HTTPError
• Added test coverage for transport error scenarios
• Added pytest to optional dependencies to satisfy flake8-requirements

[nitpick] Function docstring should use triple quotes for multi-line format consistency with other test functions.
