Remove calls to querystring.queryParamsStringify

[jeffdyke]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch @ory/hydra-client-fetch@v2.4.0-alpha.1 for the project I'm working on.

I've run into queryParamStringify is not a function repeatedly. Mainly after creating a production bundle using rollupjs with a mimicked directory structure. From the documentation it seems that queryParamStringify had been removed when querystring was removed, yet it is still called in runtime.ts

  get queryParamsStringify(): (params: HTTPQuery) => string {
        return this.configuration.queryParamsStringify || querystring;
    }

This has not really solved my problem yet, but i plan on this being my next attempt. If there is a canonical way to handle this, please let me know. Thanks!!

Here is the diff that solved my problem:
