fix(esbuild): call the hook function properly in the bundler register

[sabrenner]

What does this PR do?

Calls the hook function properly in bundler-register.js - it's possible for a hook to be an object with a hook function, and not always a hook function directly.

Failure from added test when I reverted the solution

     Command failed: node ./build-and-test-openai.js
Could not store tracer configuration for service discovery

        hooks[payload.package]();
                              ^

TypeError: hooks[payload.package] is not a function

Node.js v22.13.1

Motivation

Closes #5925

That issue reported the problem for OpenAI, but by looking at hook.js, this would also be a problem for vitest, langchain, and @vitest/runner.
