NumberBox TextAlignment property is missing

[bogdan-patraucean]

Describe the bug

I want to center the text inside a NumberBox, but the TextAlignment property available in this documentation can't be used with WinUI 3.

Steps to reproduce the bug

1. Use a NumberBox control with WASDK 1.1 and WinUI3.
2. Try to use the TextAlignment property, spoiler alert: not available!

<NumberBox Width="100" Value="10" TextAlignment="Center"></NumberBox>

Expected behavior

I expect the property to be available for use as it's part of the documentation and also added in WinUI library two years ago according to this PR.

I think the reason this isn't available is because it's marked as an experimental API, so it won't be in release builds.
@ranjeshj @MikeHillberg Is this something we can change?

I just found that this has been asked before in #4697

There's a suggestion there for if you want this right away: #4697 (comment)

I'm going to close this issue as a dupe of that one, just because the other issue already has an internal task tracking it (https://task.ms/32309254). I'm going to continue to work on getting this API promoted to stable.

Ok, @krschau, I hope we will see this soon as available.

For those who needs this immediately, I have published NumberBoxEx for this. You can get it as NuGet package.
