cleanup(angular): set target version to v22 for the decorate cli script deprecation warning (#31170)

## Current Behavior

The deprecation warning for the old script to decorate the Angular CLI
doesn't state the version in which it will be removed. This was
intentional to allow sufficient time for users to migrate away from it.

## Expected Behavior

The deprecation warning for the old script to decorate the Angular CLI
should state that it will be removed in Nx v22. It has been a long time
since it was deprecated, and it should have provided more than enough
time for users to move away from it.
