feat: Support manifest path to project directory

[blmaier]

Allow pixi-pack pack <manifest-path> to accept a path to a project directory. This ports the same feature added to upstream Pixi here prefix-dev/pixi#2716.

This also adds an additional check if the manifest path is invalid and display an error.

Fixes: #93

Motivation

This makes pixi-pack align with how pixi --manifest-path works.
This fixes the bug in #93 where if a directory is used for pixi-pack pack <directory>, pixi pack doesn't handle it correctly and searches the directory's parent for the pixi.lock

looks good, thanks!

[delsner]

Thanks, could you add a test please?

[blmaier]

I added an integration test, and that test is passing. However now a different macos started failing. It's not clear to me why, as it passed the previous run and it doesn't appear to be related to my changes 😕

[delsner]

Can you please try to add the following @blmaier? I can't push to your branch.

this is not necessary as 0.41.2 just got pulled because of prefix-dev/pixi#3112

rerunning ci works ✅
