Add an XML schema for documentation
This makes it easier to spot syntax errors when editing the
class reference. The schema is referenced locally so validation
can still work offline.

Each class XML's schema conformance is also checked on GitHub Actions.

[StyleBox] used when the [OptionButton] is focused. The [code]focus[/code] [StyleBox] is displayed [i]over[/i] the base [StyleBox], so a partially transparent [StyleBox] should be used to ensure the base [StyleBox] remains visible. A [StyleBox] that represents an outline or an underline works well for this purpose. To disable the focus visual effect, assign a [StyleBoxEmpty] resource. Note that disabling the focus visual effect will harm keyboard/controller navigation usability, so this is not recommended for accessibility reasons.
