Change the reference document link

[ashWhiteHat]

Hi there!
I modified the document link and fixed some typos.
When I click the document link, there is a 404 error so I set the link about it.
But I don't know about the other bellow three documents link.

And when I ran $make doc command the error happened because of the toolchain version problem.
The error is following and the issue is here.

(base) ➜  plonk git:(master) make doc
   Compiling syn v1.0.72
    Checking crossbeam-epoch v0.9.5
error[E0433]: failed to resolve: could not find `addr_of` in `ptr`

Hi, thanks for the PR!

LGTM but the toolchain needs to be changed to match

plonk/rust-toolchain

Also, please add the changes under Unreleased section in CHANGELOG.md

Hi @CPerezz
Thank you for the review.
I fixed it according to your review.
Please confirm.
By the way, is there any developer community like discord?
I'd like to ask some questions about this implementation 😎
Thank you!

Hi, all seems nice. I'd maybe ask for an edit of the commit message of e38fe5c to something like: Update CHANGELOG.md. Which follows the same format as the others.

For the rest, looks fine!

You can use Github Discussions!! We don't have any other places that I'm aware.
