Improve Tabs error message for wrapped TabItem components

[Patilpradnesh]

Summary

This PR improves the error message thrown by the <Tabs> component when a non-<TabItem> child is provided.

The goal is to clarify that wrapper or custom components around <TabItem> are currently not supported by the existing validation logic, which checks the direct React element type.

Changes

• Improved the <Tabs> child validation error message to mention unsupported wrapper/custom components.
• Updated the related test snapshot to match the new error message.

Context

This change is motivated by the discussion in the linked issue, where users attempted to wrap <TabItem> in custom components and encountered a confusing error.

I intentionally started with an error-message-only change to avoid modifying core behavior without guidance, and I’m very open to iterating on this approach if relaxing the validation is preferred.

Thanks for giving it a try but we don't want to imporve the error message. Instead we want to allow the composition pattern described by the user, see my comment in #11672 (comment)

[Patilpradnesh]

Thanks for the clarification Sir — that makes sense, and sorry for the confusion on my side.

I understand now that the goal is not to improve the error message, but to relax or rework the validation so that wrapper/composition patterns around <TabItem> are supported.

I’ll re-read your comment in #11672 and take a closer look at how the validation could be adjusted to allow this pattern while still preventing obvious misuse.

Happy to iterate on this direction — thanks for the guidance.
