Provide annotations without setting up LSP config using command #12
Description
Currently the user need to run Tarantool: initialize VS code extension in existing... for annotations to work. For sure, it works not so well as setting up the annotations automatically. When the extension is updated the old paths might break. Also, it's not cool to ask the user to perform some extra actions.
It might be fixed by providing extra LSP configuration with Tarantool annotations. It needs a little bit of extra support from the language server and from the EmmyLua extension for the Tarantool extension to be able to use non-workspace specific configs.
