fix(FocusTrapZone): Do not force focus inside focus trap zone on outside focus

[sophieH29]

Popup in Menu scenario was broken due to a recent focus trap zone update to the Fabric latest version.

For now, switching it back to Stardust default behavior, we will investigate later how to align.

Keeping some context for the future here:

This behavior changed between different versions of (Fabric) FocusTrapZone. So reverting to the previous behavior as it breaks some of the scenarios in Stardust.

To use the default Fabric behavior, we can still use

trapFocus={ {
  forceFocusInsideTrapOnOutsideFocus: true
} }

We should probably use false for popup by default and true for dialog (?) but it requires some testing.
