Missing @var annotation for scalars that provide default values

Thanks for putting all the work into fixing this and other issues

The patch still applies.

After a visual inspection of the patch ....Yep all these changes look good to me.

Checked those over; it's easy to see that the correct data type is given in each case and that they're unlikely to allow a different data type (or NULL since they're being initialized to other things).

I opened the file to check this one since it was beyond the context lines:

protected $profile = 'minimal';

So that's correct too.

Committed to 8.5.x, and cherry-picked to 8.4.x as a pure docs improvement. Thanks!
