Hi!

First of all, thank you for the great project!

When using `@codemirror/lsp-client`, the `diagnostics.ts` file requires `@codemirror/lint` to be installed at compile-time:

```auto
import {setDiagnostics} from "@codemirror/lint"

```

[Repo link](https://github.com/codemirror/lsp-client/blob/main/src/diagnostics.ts#L2)

However, it’s not in the package.json file of the repo, causing the bundler to get confused if it’s strict about deps.

Should I make a PR adding it as a dependency?

Thanks!

Indeed, I forgot to declare that dependency! Thanks for spotting that. This patch adds it.
