Update agent to handle updates from `import-in-the-middle@1.11.1`

[bizob2828]

Description

It looks like this PR, broke our wrapReturn shim function which wraps an export in a Proxy. After updating to import-in-the-middle@1.11.1 you get

TypeError: getters.get(...)[name] is not a function
    at Object.get (register.js:20:37)
    at Object.set (shimmer.js:648:30)
    at DatastoreShim.wrapEachProperty (shim.js:347:20)
    at Array.forEach (<anonymous>)
    at DatastoreShim.wrap (shim.js:334:14)
    at DatastoreShim.wrapReturn (shim.js:398:15)
    at instrumentPGNative (pg.js:61:10)
    at initialize (pg.js:33:12)
    at _firstPartyInstrumentation (shimmer.js:711:29)
    at loadInstrumentation (shimmer.js:675:25)

It's failing when we try to assign the exported module property as wrapped here

Steps to Reproduce

1. npm i import-in-the-middle@latest
2. npm run versioned:internal:major pg-esm

Expected Result

Tests pass

Actual Result

Tests fail
