Automatically publish updates to Homebrew on each release

We should add a GitHub action that automatically runs a command to update Homebrew's kotlin-lanugage-server formula in each new release of the server. This will allow users to simply run brew update to fetch the latest language server and will reduce the maintenance costs in manually updating Homebrew with the latest artifacts.

We could consider Homebrew bump formula or other similar actions that might help.
