The E2E schematic will now (as it did previously) skip adding dependencies if they already exist within the `package.json` regardless of the specifier. This is accomplished with the `existing` option for the `addDependency` rule which allows defining the behavior for when a dependency already exists. Currently the two option behaviors are skip and replace with replace being the default to retain behavior for existing rule usages.
