fix(editor): Update config sent to language server (#6724)

Syncs up the options from the language server `Options` struct with the
values that the extension supplies.

I tend to avoid `toJSON` because it will be used by `JSON.stringify`
when called and it's not well known.
There's no reason that `LanguageServerConfig` and `Config` have to both
exist, but I think two types is easier to understand.
