fix(@angular/cli): update the update command to fully support Node.js…

… v16

Node.js v16's `fs.rmdir` will now throw an `ENOENT` error if the path does not exist. `fs.rm` is now the preferred option when using Node.js v16 but since this function is not available on Node.js v12 both are tried with `fs.rm` given preference.
In the case of the update command, the usage was guarded by a try/catch block with the downside of leaving the `fs.rmdir` being that a deprecation warning would be shown when running the command which is not ideal.
