Feature/pixi fixes

[blooop]

This fixes some deprecation warnings that appear when using the latest version of pixi (0.49.0)

  ⚠ The `depends_on` field is deprecated. Use `depends-on` instead.

 WARN Encountered ambiguous version specifier `3.27.6`, could be `3.27.6.*` but assuming you meant `==3.27.6`. In the future this will result in an error.
 WARN Encountered ambiguous version specifier `1.11.1`, could be `1.11.1.*` but assuming you meant `==1.11.1`. In the future this will result in an error.

I also ran pixi update to get the latest versions of the pixi dependencies.

Pixi > 0.44 allows us to specify a pixi-requires to pin pixi itself. However, rerun is below that so maybe we don't update that until rerun itself comes forward.
