This change removes all direct usage of the `node_modules` directory from the version command. This provides improved support for yarn PnP as well as prevents a crash when a workspace does not have a `node_modules` directory.
Fixes#10474
When testing a local CLI build with `npm link @angular/cli`, if you run `ng version`,
you currently see:
Angular CLI: local (v8.1.0-beta.2+24.3bb67d8.with-local-changes, branch: version)
if the Git branch is `fix/version`.
Whit this PR, `ng version` now displays the proper Git branch name:
Angular CLI: local (v8.1.0-beta.2+24.3bb67d8.with-local-changes, branch: fix/version)
