fix(engine.io-parser): do not expose the TransformStream type

The previous commit [1] tried to work around the fact that the
TransformStream object is not exposed in the global scope in the
`@types/node` package, even though it is since Node.js `v18.0.0`.

Unfortunately, it created two new issues:

- using an older `@types/node` version (before v16) would fail with:

> error TS2307: Cannot find module 'node:stream/web' or its corresponding type declarations.

- browser-only environments would somehow include the node types,
leading to conflicts like the return value of the setTimeout() method
