Vim/Emacs integration docs reference archived projects

~~[Vim editor integration docs](https://flow.org/en/docs/editors/vim/) reference `flow-language-server`, which is archived~~
[Emacs editor integration docs](https://flow.org/en/docs/editors/emacs/) reference `flow-for-emacs`, which is archived

It'd be great to have full examples on these pages rather than mostly linking to other projects. I switch between editors often and flow is somewhat of a chore to setup in each editor I try. I think smoother integration in general would make Flow that much better.

Edit: I may have been wrong about Vim docs, `flow-language-server` is the ale setting, not a reference to the archived project. I may have uncovered a bug and blamed the docs.
