Updates to a supported version of node and removes node-sass to fix installation issues related to its deprecation.

Using npm pack and pulling this into EDSC and doing some regression testing I wasn't seeing any issues. I think those GH actions jobs there needs to be a config change into the settings though "the waiting for status hydrogen:) ones that is I ran into a similar issue in graphql but, don't have the permissions to update that one
