Pixi 0.28.1 breaks pypi dependency installation

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 --version
pixi 0.28.1
$ pixi init
✔ Created /home/user/test/pixi.toml
$ pixi add python
✔ Added python >=3.12.5,<4
$ pixi add --pypi ctranslate2==4.3.1
  × failed to solve the pypi requirements of 'default' 'linux-64'
  ├─▶ failed to resolve pypi dependencies
  ╰─▶ Because ctranslate2==4.3.1 has no wheels with a matching Python ABI tag and you require ctranslate2==4.3.1, we can conclude that your requirements are unsatisfiable.

$ pixi list -x
Package  Version  Build               Size      Kind   Source
python   3.12.5   h2ad013b_0_cpython  30.2 MiB  conda  python-3.12.5-h2ad013b_0_cpython.conda

Issue description

It works in Pixi 0.28.0 but not in 0.28.1. Pixi 0.28.1 fails with the error "no wheels with a matching Python ABI tag".

Expected behavior

With pixi 0.28.0

$ pixi self-update --version 0.28.0
✔ Pixi will be updated from 0.28.1 to 0.28.0
✔ Pixi archive downloaded.
✔ Pixi archive uncompressed.
✔ Pixi has been updated to version 0.28.0.
$ pixi init
✔ Created /home/user/test/pixi.toml
$ pixi add python
✔ Added python >=3.12.5,<4
$ pixi add --pypi ctranslate2==4.3.1
✔ Added ctranslate2==4.3.1
Added these as pypi-dependencies.
$ pixi list -x

I think this was fixed by #1925, release coming soon!
