Reproducible example

[project]
description = "A description"
name = "test"

[project.entry-points.entry]
entry = "some.entry

$ pixi install --manifest-path pyproject.toml
Error:
  × Unexpected keys, expected only 'name', 'version', 'description', 'readme', 'requires-python', 'license', 'license-files', 'authors', 'maintainers', 'keywords', 'classifiers', 'urls', 'entry_points',

  help: Did you mean 'entry_points'?

Issue description

This is new in 0.40.0, downgrading to 0.39.5 fixes the issue.

Per the error, updating pyproject.toml to use entry_points instead also works.

Expected behavior

Raising this as a bug because this should be allowed per the pyproject.toml spec

As hinted by the error message, pretty sure that this line

pixi/crates/pixi_manifest/src/toml/pyproject.rs

Line 115 in 4f622f5

"entry_points",

should be entry-points
