Group all Angular packages that have the same version as @angular/core, and
also show information for schematics, devkit and others that might not be
in the package.json but still installed. Those versions are important.
We're not updating this number anymore since ng init/update is gone, so at
best it's useless and at worst it's confusing since it appears on ng
version.
This commit changes 2 things:
1. Changes remaining angular-cli package references to @angular/cli.
2. Where angular-cli was mentioned as a project name, it's been changed
to Angular CLI.
Where angular-cli was meant to mean the repository name, it's been left
unchanged.
