fix: Export schema only once

[inaiat]

We have a problem using import-in-the-middle (lib embedded inside opentelemetry), because this lib intercept and register a hook of modules. I found a issue that reexport of schema module, beceuse this module is export twice on index.js.

The exception generated using import-in-the-middle, papr, and node20:

file:///Users/papr/esm/index.js?iitm=true:90
    let $schema = $1707251817792598e86e3.schema
        ^

SyntaxError: Identifier '$schema' has already been declared

    at callTranslator (node:internal/modules/esm/loader:285:14)
    at ModuleLoader.moduleProvider (node:internal/modules/esm/loader:291:30)

Node.js v20.11.0

Thanks in advanced.

Thanks for that reproducible repo!

It seems that this issue is an issue with the import-in-the-middle package. This issue seems to report the same bug like you uncovered here.

I am inclined to wait a few more days to see if this gets solved upstream. Otherwise, we can bring in this change.

Hey @avaly !
I guess that the issue is hard to resolve! So I think its easier apply the "fix".

Thank you!
