Please update the documentation for components that use [tuiTextfieldLabelOutside]="true" in the example

Hi guys,
First of all, thank you so much for your hard work on this UI, I love it!
I just spent some time struggling with both tui-input-count and tui-select sizing option. I simply couldn't find how to make the input look slimmer with the documentation information alone. No matter what value I set tuiTextfieldSize to. I couldn't find any tip online either.
The information I was missing was that I needed to import TuiTextfieldControllerModule in order to be able to use [tuiTextfieldLabelOutside]="true" like in the doc example.
This tip could save a few hours of hair pulling to users out there. I thought it would be a helpful addition to the documentation ;)
