refactor(instrumentation-http): fix eslint warnings

Fix the following eslint warnings:

```
/home/runner/work/opentelemetry-js/opentelemetry-js/experimental/packages/opentelemetry-instrumentation-http/src/http.ts
  236:41  warning  Unexpected any. Specify a different type  @typescript-eslint/no-explicit-any
  251:31  warning  Unexpected any. Specify a different type  @typescript-eslint/no-explicit-any
  252:31  warning  Unexpected any. Specify a different type  @typescript-eslint/no-explicit-any
  283:41  warning  Unexpected any. Specify a different type  @typescript-eslint/no-explicit-any
  298:31  warning  Unexpected any. Specify a different type  @typescript-eslint/no-explicit-any
  299:31  warning  Unexpected any. Specify a different type  @typescript-eslint/no-explicit-any
```

Extracted a utility function with more precise types for the job.
