make code Node ESM compatible

[trusktr]

Importing in Node.js directly, or with tools that strictly follow Node ESM spec (like Webpack), will cause an error.

Note that the import type lines don't require this, only the import lines that end up in JS.

WIthout this, bundling an app with Webpack 5 produce such errors:

Another case where patch-packet saves the day, since the pr will likely never get merged :(

Thank you @ruohki for introducing me to patch-package! For anyone implementing this, here's the patch file I used:

For posterity, seems like if apollographql/apollo-client#8218 is resolved, so will this.
