Add pypi dependencies without version specification

[Serruchox7]

Hello,

I'm used to work in Python with both conda and pip dependencies and Pixi is very fast for solving!
I'm trying to understand how the GUI could simplify my way of working but I'm facing the following issue:

• for some features (test, build, etc.), I'm used to specify pypi dependencies without specific version so I can get the updates easily;
• when I add a conda dependency, I can specify "*" and there is no version associated in the manifest;
• when I add a pypi dependency, "*" is not allowed so I specify "" (nothing), but for some packages (pandas, numpy) it adds my dependency with no version, and for some others (tensorflow, scipy, build) it adds it with a version as if I had selected "Choose version automatically";

Why is the output different according to the specified package?

The parsing used for what is specified in the gui is not the same as the parsing in the TOML file.

This comes down to conda supporting numpy=* but pypi doesn't support that notation.

I think we could improve the UX by approving whatever is possible in the TOML file.
