No errors for ESM module resolution, while errors are expected

The lib: https://www.npmjs.com/package/@microlabs/otel-cf-workers

The analysis: https://arethetypeswrong.github.io/?p=%40microlabs%2Fotel-cf-workers%401.0.0-rc.23

Shows all is ok, however, if we navigate to the lib, we'll clearly see incorrect import statement at https://github.com/evanderkoogh/otel-cf-workers/blob/v1.0.0-rc.23/src/instrumentation/env.ts#L6

I have also checked `dist` in the npm package, the same import.
It fails the build locally trying to use this lib in ESM project.

Reproduce the analysis for @microlabs/otel-cf-workers@1.0.0-rc.23 and compare it with the import in src/instrumentation/env.ts at line 6 and the corresponding dist output. Trace why the ESM resolution problem is accepted, then verify that this package produces the expected error.
