Improve NoScript documentation
[A user asks](https://blog.torproject.org/comment/277954#comment-277954) for a better documentation for NoScript 10.
> On the introductory page you have a link "FAQ", and there you will find a link "NoScript FAQ", which will open the FAQ for the old noscript version(s). There is no official documentation for noscript. All you can get is a link to a blog writer giving "basic" information about the new noscript. This is very basic indeed and not an official documentation.
> Another link will redirect you to a page inteding to give an overview of the new noscript in a nutshell. A nutshell is not enough for understanding the new noscript - as you can see from the "226 Responses to “NoScript, "Quantum" vs "Legacy" in a nutshell”.
The [current/old FAQ](https://www.torproject.org/docs/faq) does not link the NoScript FAQ, while the [support page](https://support.torproject.org/#tbb) does.
[I'm having a problem with NoScript.](https://support.torproject.org/#tbb-25) links to the NoScript FAQ which i think is fine although it may not reflect [latest changes](https://noscript.net/changelog)?
BTW `Should I install a new add-on or extension in Tor Browser, like AdBlock Plus or uBlock Origin?` is listed twice ([faq-3](https://support.torproject.org/#faq-3) and [tbb-14](https://support.torproject.org/#tbb-14))
