Unexpected conflict between requirements and constraints file

[eshenayo]

Description

Encountering an unexpected error while running: python3.11 -m pip install -r requirements.txt -c constraints.txt

In the requirements.txt file line 6 is just faster_whisper the constraints file has the line:
whisper-timestamped @ git+https://github.com/linto-ai/whisper-timestamped@b8cfd26ac0109b84d3252638ad882ab77e0dba2e
When the constraints file is changed to be a version instead of git url, the error resolves.

Expected behavior

That @ urls are respected in the constraints.txt file.

pip version

24.3.1

Python version

3.11

OS

Ubuntu 22.04

How to Reproduce

1. Create a requirements.txt file with the contents:
   git+https://github.com/linto-ai/whisper-timestamped git+https://github.com/openai/whisper.git git+https://github.com/suno-ai/bark.git
2. Create a constraints.txt file with the contents:
   openai-whisper @ git+https://github.com/openai/whisper.git@90db0de1896c23cbfaf0c58bc2d30665f709f170 suno-bark @ git+https://github.com/suno-ai/bark.git@f4f32d4cd480dfec1c245d258174bc9bde3c2148 whisper-timestamped @ git+https://github.com/linto-ai/whisper-timestamped@b8cfd26ac0109b84d3252638ad882ab77e0dba2e
3. Run: python3 -m pip install -r requirements.txt -c constraints.txt
