fix(@angular/cli): ensure lint command auto-add exits after completion

When no lint target is present for a project, the command will ask if linting should be added to the project.
However, after adding the package, the command incorrectly kept executing and then failing due to the lint command not being fully setup yet.
Instead, the command will now exit after adding the linting package. This also allows inspection and/or adjustment of the linting configuration prior to actually linting.

Fixes: #22937
