Fix build for pontoneer and address feedback

[winding-lines]

Checklist

• My recipe.yaml file specifies which version(s) of MAX is compatible with my project (see here for an example). If not, my package is compatible with both 24.5 and 24.6.
• License file is packaged (see here for an example).
• Set the build number to 0 (for new packages, or if the version changed).
• Bumped the build number (if the version is unchanged).

@winding-lines - modular-community doesn't support building packages for nightly.

If you want to make your package available to use in the interim without going through modular-community you can set it up to use the pixi-build-backend (some links to examples of how to use it: https://forum.modular.com/t/addition-of-pixi-build-mojo-pixi-backend/2057?u=duck_tape)

You can then depend on your package with pixi via pontoneer = {git=...}.

I'm going to revert 223 via #225 for now so that any other packages that get merged in can build.

Hi @winding-lines, apologies for the delay on this! Here's the error that's happening when we build the PR:
