fix: Revert "fix: resolve cjs deps as cjs instead of esm (#362)" (#365)

This reverts commit 1eba4d5.

The fix in the original PR did solve the problem of tracing a dependency
being loaded from an ESM file via `require()`, but also caused a
regression where a simple `.mjs` file with ESM imports was failing. I
have a test (#364) for that.
