feat: Bump vscode language server dependencies (#521)

The vscode language server dependencies in this extension is 2 major
versions behind. There were important changes [between v7 and v8](https://github.com/microsoft/vscode-languageserver-node?tab=readme-ov-file#3170-protocol-800-json-rpc-800-client-and-800-server).

* Updated utilities that now return void promises
* Added a `deactivate` function to the extension to which is now
  recommended practice
* Replace `onReady` with `onStart` as described in the changelog
* Make the log function types more resilient - the `RemoteConsole`
  contains functions that are not just log functions.

Lots of reports have recently reported that 'stylelint does nothing' -
running the extension in debug mode to break on unhandled excpetions,
it's easy to see that there is client protocol changes since headers are
malformed in many requests.
