[Feature] completionItem/resolve doesn't resolve additional details

[yamsergey]

Description

According to LSP specification client can request additional details completion items fetched with textDocument/completion by calling completionItem/resolve.

Problem

There is no additional details provided.

P.S.

Now I mostly interested in documentation field when it's available.

We've recently addressed this issue and implemented a much better completion support, using exactly the same infrastructure as IntelliJ. To be released soon.

May I ask if it goes for diagnostics as well? Because now it's a bit unorthodox sometimes 😅
