fix: revert "load sourcemaps alongside modules (#11576)"

[benmccann]

Description

Reverts #11576 as it's causing failures on the ecosystem CI: #11576 (comment)

Additional context

I'd love to get better source map support added, but source map support is pretty finicky in my experience and the PR being reverted didn't have any tests. We should probably make sure anything source map related has tests and is run against the ecosystem CI before merging on the next attempt. We reverted another attempt at source map support earlier for similar reasons

Thanks Ben, I agree. @Vap0r1ze let's try again for 4.2, it was good at least to check how it worked in the wild and find out these issues. Thanks!
