Shared semantic-release configuration for LabShare Github projects

/* 
  This file is called during "prepareCmd" step of "@semantic-release/exec" 
  in lib.js configuration file. It will update the root package since 
  commit-analyzer plugin only updates package.json and package-lock.json
  files inside the "/dist" folder.
  Once this has run, git and github plugins will run with correct version 
  in root files, allowing for automatic version update commit .
