fix: use correct arg name in z.assert.length.neq

[RafDevX]

Trying to use assert.length.neq currently fails because rhs does not exist; this PR fixes that

Could you add a test that checks that this actually resolves the issue? Just using the assertion should suffice I think.

Ok, I've added a test. I'm not sure how to generate a corresponding ref/1.png, so perhaps you can do that yourself if you would like to have it too? I've enabled "Allow edits by maintainers" for this PR

Unfortunately I don't really have time to prepare the tooling for this. The original test references were created with typst-test, but that version is quite old and doesn't have release artifacts. You could try installing tytanic 0.2.0-rc1.

I suggest creating the test freshly with tt add assertions/length or tt new assertions/length to ensure it has references, overwrite the generates test.typ file with your new test and run tt update to update the reference.

I'm unsure if that will work exactly the same, I don't remember when the typst-test -> tytanic rename happened anymore.

Closed as merged in a different PR because I absolutely suck at git. Thank you :)
