WIP: Log message

This fixes #10532 by properly making use of `itemDefaults.data` when
that is sent along next to completion `items`.

With this line here we tell the language server that we support `data`
in `itemDefaults`, but we actually never checked for it and never used
it:


a0d7ec9f8e/crates/lsp/src/lsp.rs (L653)

In the case of `tailwindcss-language-server` that means that most of the
items it returns (more than 10k items!) were missing the `data`
attribute, since the language server thought it can send it along in the
`itemDefaults` (because we advertised our capability to use it.)

When we then did a `completionItem/resolve`, we would not send a `data`
attribute along, which lead to an error on the
`tailwindcss-language-server` side and thus no documentation.

This PR also adds support for the other `itemDefaults` that could be
sent along and that we say we support:


a0d7ec9f8e/crates/lsp/src/lsp.rs (L650-L653)

`editRange` we handle separately, so this PR only adds the other 3.

Release Notes:

- Fixed documentation not showing up for completion items coming from
`tailwindcss-language-server`.
([#10532](https://github.com/zed-industries/zed/issues/10532)).

+We have two cloudflare workers that let us serve some assets of this repo
+from Cloudflare.
+
+* `open-source-website-assets` is used for `install.sh`
+* `docs-proxy` is used for `https://zed.dev/docs`
+
+On push to `main`, both of these (and the files they depend on) are uploaded to Cloudflare.
+
+### Deployment
+
+These functions are deployed on push to main by the deploy_cloudflare.yml workflow. Worker Rules in Cloudflare intercept requests to zed.dev and proxy them to the appropriate workers.
+
+### Testing
+
+You can use [wrangler](https://developers.cloudflare.com/workers/cli-wrangler/install-update) to test these workers locally, or to deploy custom versions.
