Do not resolve more completion fields (#19021)

As Zed instantly shows completion items in the completion menu, and the
resolve will cause the details to appear, flickering.
We can safely resolve the `documentation`, `additionalTextEdits` and
`command` fields, the rest should be resolved eagerly for now.

Release Notes:

- Fixed completion menu rendering
