Documentation of Vim and Emacs Setup Outdated

[lassepe]

It seems like the documentation is outdated for vim and emas. The examples still suggest that one should handle a Dict as the last argument to the LanguangeServerInstance. However, it seems like this is a function now (error handler). Unfortunately, I don't know enough about the internals to update the documentation myself and make a PR, all I can tell is that the current documentation seems outdated.

I've updated the Emacs wiki page to merely point at the appropriate packages. Should only be as outdated as the lsp-julia and eglot-jl packages are now. :)

Excellent, thanks!
