lock: incompatibility use_uv and @ http://....tar.gz

[paugier]

Describe the bug

Defining a dependency as

dev = ["mdformat-py-edu-fr @ http://foss.heptapod.net/py-edu-fr/mdformat-py-edu-fr/-/archive/0.1.1/mdformat-py-edu-fr.tar.gz"]

with use_uv, I get when locking

pdm.termui: Error occurs
Traceback (most recent call last):

KeyError: 'url'

Indeed, the uv lock file contains:

[[package]]
name = "mdformat-py-edu-fr"
version = "0.1.1"
source = { url = "http://foss.heptapod.net/py-edu-fr/mdformat-py-edu-fr/-/archive/0.1.1/mdformat-py-edu-fr.tar.gz" }
dependencies = [
    { name = "jupytext" },
    { name = "mdformat-myst" },
]
sdist = { hash = "sha256:124488d1796a7ad5f98b1365fe00ff3e71846fd1f91d46e54f8b73c0cdbd78a1" }

I guess I could work on a workaround in pdm/resolver/uv.py (somewhere around https://github.com/pdm-project/pdm/blob/main/src/pdm/resolver/uv.py#L170) but I first like to have feedback on this bug and on the proper way to solve it.

To reproduce

Lock with use_uv and

dev = ["mdformat-py-edu-fr @ http://foss.heptapod.net/py-edu-fr/mdformat-py-edu-fr/-/archive/0.1.1/mdformat-py-edu-fr.tar.gz"]

Expected Behavior

PDM should produce a lock file.
