fix: correct variable name in source-map transform

[SimenB]

A linter should probably have caught this

/cc @bcoe fixes the error in Jest

A linter would have caught issues like this one 😅

@SimenB maybe worth adding a test that traverse this path? Not sure how hard that's gonna be though

[SimenB]

Sourcemaps are such a magical black box to me still, even after I spent quite a few hours trying to grasp the basics of it :P Not sure which case triggers this branch

[thymikee]

Haha, that's exactly why I added "Not sure how hard that's gonna be though" :D

@loganfsmyth any thoughts on a way to exercise this line? @SimenB if you saw fit to plop in a linter (which I think we should have setup on the other packages perhaps?) it would be amazing.

[SimenB]

Can this be merged and released in the meantime, the current prerelease is pretty broken due to this 🙂

I can send a PR for some linting, sure

@SimenB 👋 working on landing it now.
