fix(@angular/cli): disable version check when running ng completion commands

Running autocompletion with `14.0.1` installed globally in a `14.0.0` project logs the version warning in a very annoying fashion:

```
$ ng verYour global Angular CLI version (14.0.1) is greater than your local version (14.0.0). The local Angular CLI version is used.

To disable this warning use "ng config -g cli.warnings.versionMismatch false".
sion
```

This adds an exception for `ng completion` commands to avoid this edge case.
