the code looks good, I've slightly updated the documentation wording and some of the examples to adhere to our own recommendation about tabIndex

What is the point of setting the tabIndex to 0 when the panel is disabled? It will never be 0.

INSTUI-4878
Summary
The component was hardcoding
tabindex="0"on all panels.According to WCAG guidelines, this should only be set when panels don't contain focusable elements, otherwise it creates unnecessary tab stops.
Adds optional
tabIndexprop toTabs.Panelto allow proper WCAG-compliant focus management.Developers can now set
tabIndex={-1}for panels with focusable content ortabIndex={null}to omit the attribute entirely.Changes
tabIndexprop toTabs.Panelto allow proper WCAG-compliant focus managementtabIndex?: number | nullprop (defaults to0for backwards compatibility)Test plan
On the documentation page, verify the correct focus handling of Tabs.Panel.
