docs: qwik install and troubleshooting instructions

[literalpie]

What I did

Add some setup docs for Qwik that were not included when I created the framework.

How to test

I tested this by launching the front-page project, with a copy of the docs folder with these changes (the yarn link workspace command didn't work for me).
I confirmed that the added docs do show up in the docs site:

@literalpie, thanks for taking the time and effort into this pull request and adding the initial set of documentation for the QWIK framework. Appreciate it 🙏 !

Regarding this item:

I tested this by launching the front-page project, with a copy of the docs folder with these changes (the yarn link workspace command didn't work for me).

That's something we want to revisit at some point as it may be cumbersome for not only you or any other contributor to set up the documentation and preview it locally. If you're ok with adding an issue in the Storybook frontpage repository and mentioning what you've experienced, we'd appreciate it. So that we can look into it and fix it so that you or anyone else doesn't need to manually copy over the documentation folder.

With that out of the way, it's all good on my end, and I'll merge this in a bit, as soon as the checklist clears.

Hope you have a great day.

Stay safe
