Add default lsp for toml

Seems like it supports schemas which match against files like Cargo.toml, used for auto-completion, hover docs, etc. Maybe we can leverage it for helix's config.toml.

From the docs (here) it looks like this should be

Suggested change

	language-server = { command = "taplo", args = ["lsp", "stdio"] }
	language-server = { command = "taplo-lsp", args = ["run"] }

But maybe I'm just running an out of date binary locally? I'm running taplo-lsp 0.2.6 and maybe the most recent taplo has consolidated the LSP and CLI binaries?

taplo-lsp can no longer be installed by itself, it can only be run from taplo lsp.
I think it was unified all in one.

In this section it says install with cargo install taplo-lsp but throws an error.

I install taplo-cli and it runs with the simple taplo command. I attach a screenshot.

Ah ok, yeah looks like my package manager is behind on taplo versions. This looks good then 👍

Thanks!
