Closes https://github.com/zed-industries/zed/issues/21205
Zed does completion resolve on every menu item selection and when
applying the edit, so resolving all completion menu list is excessive
indeed.
In addition to that, removes the documentation-centric approach of menu
resolves, as we're actually resolving these for more than that, e.g.
additionalTextEdits and have to do that always, even if we do not show
the documentation.
Potentially, we can omit the second resolve too, but that seems
relatively dangerous, and many servers remove the `data` after the first
resolve, so a 2nd one is not that harmful given that we used to do much
more
Release Notes:
- Reduced the amount of `completionItem/resolve` calls done in the
completion menu
