♻️Refactoring | Use XamlStyler

Hey team,

I see a few opportunities to improve the quality of our codebase.
It would be cool if we could:

1. Start using XamlStyler (https://github.com/Xavalon/XamlStyler). The plugin is available for both VisualStudio and Rider. It is super easy to get going; I normally use the default formatting configuration only with a few slight modifications.
   The benefit is that our xaml code will be consistently formatted across the project.
   ...

If you guys agree with it, I am happy to implement both tasks.
(cc: @matt-goldman, @JackDevAU)

It's required to:

• Create a draft of Settings.XamlStyler
• Discuss formatting details with @matt-goldman and make changes to the draft
• Format all xaml files
• Update documentation explaining how devs should set up their IDEs so that Settings.XamlStyler is picked up

Start by drafting Settings.XamlStyler, then review the formatting details with @matt-goldman before applying them to all XAML files. Update the developer documentation to explain how IDEs should be configured to use the settings file; done means the checklist is complete and the project’s XAML is consistently formatted.
