Subject: lsp: Resolve completion items missing documentation on idle (#4406)

Some language servers may not send the `documentation` field if it
is expensive to compute. Clients can request the missing field with
a completionItem/resolve request.

In this change we use the idle-timeout event to ensure that the current
completion item is resolved.---
