Yarn: skip unplugging dependencies in the regular workflow

Set the "enableScripts" .yarnrc.yml option to false, which avoids the
unplugging of dependencies that have postinstall scripts.

The unplugged content is necessary for the Yarn project to run, but
since a "yarn install" is expected to happen during the build phase for
a regular workflow project, this content will still be generated as
expected.
