Improve CLI docs (#1404)

* Improve CLI docs

* Fixed all the typos (hopefully).
* Improved the bad English. This encompasses grammar, vocabulary, generally awkward phrases, etc. The result is easier to read and understand, and in some cases shorter.
* Made some formatting improvements. This includes making formatting more consistent, but I changed some of it to be better, at least in my opinion.
* Removed certain unnecessities, the biggest one being the commands documentation. I think this is unnecessary because of the `dx --help` command. It also needs to be updated every time a command gets added/updated/removed. It doesn't really provide much extra insight than `dx --help`.
* Improved plugin documentation. I added a warning to ignore all of it, which is ironic, but the fact is that plugins are probably going to change. But by the time I learned that, I already made some changes to the plugin docs. This includes a better guide on how to get started (although still bad since the plugin system is too messy), and some general changes like the aforementioned English or formatting.
* And more. I can't list it all, but I didn't use any destructive changes. The content might be reformatted (to be shorter or easier to understand), but the meaning isn't lost.

* Fix grammar in packages/cli/docs/src/creating.md
