Update emacs support table

[kurnevsky]

• worksheets with decoration protocol are fully supported
• lsp-metals supports quite a lot of metals extensions
• source file analyzer commands are supported

btw, how metals is installed in vim? I wonder if I should change emacs to single click because it can be installed automatically if lsp-metals is present :)

I think via coursier, but most likely @ckipp01 can correct me.

LGTM!

Well, emacs can install metals via coursier as well :)

Hmm... actually vim might also be doing that without a need to provide a bootstraped binary. By all means if it only needs lsp-metals then I would say it's "one click" installation

[kurnevsky]

ok, changed that line. It might not always work, though, because we rely on automatically downloaded binaries. I'm not sure how it works for apple M1 (probably it emulates x86 automatically?), but for nix/guix these binaries don't work. Not sure, maybe we should change it to jars...

Yup, under the hood it just uses coursier to bootstrap everything.
