Describe the feature you'd like to request

A first release of a cedar-language-server is now available in the cedar-policy repo.

Investigate the functionality exposed by this LSP and migrate from a custom WASM implementation to using this create. Not all functionality include today may be exposed by cedar-language-server, while others are more robust.

Describe alternatives you've considered

Implement any additional functionality in the existing code base in case LSP changes behaviors that might be considers a breaking change.

Additional context

The cedar-language-server will be used in other contexts/editors so migration results in a more consistent developer experience.

Is this something that you'd be interested in working on?
