This allows function call (i.e. snippet) completion with
`typescript-language-server`. So far that didn't work, because
`typescript-language-server` doesn't respond with `insertText` when
getting the completions, but only when then sending
`completionItem/resolve` requests. See:
https://github.com/hrsh7th/nvim-cmp/issues/646#issuecomment-992765479
What this PR does is to support text edits in the response to
`completionItem/resolve`, which means updating the completion item.
It then enables this feature by default for
`typescript-language-server`.
TODOs:
- [x] Make this work over collab
- [x] Test that this doesn't break existing language server support
- [x] Refactor duplicated code
Release Notes:
- Added support for function call completion when using
`typescript-language-server`. This will result in parameters being
added, which can then be changed and navigated with `<tab>`. For this to
work with `typescript-language-server`, the documentation for a given
completion item needs to be resolved, meaning that if one types very
quickly and accepts completion before `typescript-language-server` could
respond with the documentation, no full function completion is used.
