pip reports dependency conflict on itself for private package

[snaumov-sc]

Description

I have a private repository with pyproject.toml that sets package version to "0.1.0".
While I specified a dependency on it in requirements.txt of my main project in a form of git+ssh://git@gitlab.***.com/<package>.git@v0.1.0, everything was fine.

But when I tried to switch to pyproject.toml in my main project, using "<package> @ git+ssh://git@gitlab.***.com/<package>.git@v0.1.0" in dependencies section, I got the following error:

ERROR: Cannot install <package> 0.1.0 (from ***) and <package>==0.1.0 because these package versions have conflicting dependencies.   
The conflict is caused by:                                                                                                                                                    
    The user requested <package> 0.1.0 (from ***)                                                                                           
    <package> 0.1.0 depends on <package> 0.1.0 (from git+ssh://****@gitlab.***.com/<package>.git@v0.1.0)

I've tried to recreate .venv from scratch, but it didn't help.

Expected behavior

Clean install as with requirements.txt.

pip version

22.0.2

Python version

3.10

OS

Xubuntu 22.04

How to Reproduce

As I use private package, it is hard to say how to reproduce.

Can you provide a public repo that illustrates the issue?
