Add version range to pypi-dependencies when using pixi add --pypi

[FunkMonkey]

Checks

• I have checked that this issue has not already been reported.

• I have confirmed this bug exists on the latest version of pixi, using pixi --version.

Reproducible example

pixi add EduData --pypi

Issue description

Maybe I just have the wrong expectations, but when I added a package via the --pypi flag, the package was simply added like this to pyproject.toml:
dependencies = ["edudata"]

Is this the expected behaviour or should the package be added with default version ranges as discussed in #639?

Thank you

Expected behavior

Expected dependencies:
dependencies = ["edudata >=0.0.18,<0.1"]

It would make sense to be consistent between pypi and conda packages. Maybe not a bug but a enhancement?

I just want to emphasize that this "enhancment" is critical for adoption of pixi since it is needed to achieve reproducible package builds. Hope someone finds the time to tackle this one, I would but I am not experienced in Rust.

@ruben-arts I though this was already implemented with the latest release?

[ruben-arts]

I thought so too but want to make sure before closing the issue.

[ruben-arts]

This is was actually fixed already in #1508.

Closing this as fixed.

@SeanPedersen Are you trying with the latest release? If so and it still doesn't work, can you open a new issue with the non working pixi.toml/pyproject.toml?

[SeanPedersen]

Everything works as expected with the latest release, thanks a lot.
