NumberBox Description does not wrap

[agneszitte]

Describe the bug

NumberBox Description text does not wrap

Steps to reproduce the bug

Test to resize a sample app that is using this snippet of code:

    <muxc:NumberBox Header="Enter a number:"
					Minimum="10"
					Maximum="100"
					PlaceholderText="10"
					Description="This is a description which is shown below the NumberBox" />

Expected behavior

NumberBox Description should wrap (when resizing the app or when placed somewhere in the UI when it should wrap)

Screenshots

• Fine when there is enough place
  

• But not wrapping when there is not enough place

ContentPresenter should text wrap. We can fix this in WinUI3.
