fix(showcase): V11 hide API tab when API page is not available

[Coderxrohan]

Problem

In the PrimeReact v11 showcase, the API tab is rendered for all components.
For some components (e.g. Tabs), an API page does not exist, so clicking the API tab navigates users to a non-existent route and results in a 404.

Solution

This PR updates the documentation tab UI to conditionally hide the API tab when an API page is not available for a component.

• UI-level fix only
• No routing changes
• No redirects
• Prevents navigation to dead /api links
• Aligns behavior with PrimeReact master

Result

• Components without API pages → API tab is hidden
• Components with API pages → API tab remains visible and works as expected
• Direct URL access to non-existent /api routes remains unchanged (404), by design

Scope

• apps/showcase/components/docs/doc-tabs.tsx

Context & Resolution Summary

• The issue was originally reported in [v11] docs: API page for Tabs component in the docs returns a 404 #8388.
• The fix was implemented on the master branch, merged successfully, and the issue was closed.

Follow-up for V11

• PR fix(docs): hide API tab when apiDocs are not available #8462 was initially raised to address [v11] docs: API page for Tabs component in the docs returns a 404 #8388, but it encountered branch conflicts and was therefore closed.
• Since the fix was required specifically for V11, a dedicated PR was necessary.
• PR [v11] Backport: Hide API tab when API page is not available #8465 has been created to apply the same fix to the V11 branch only.

Hi @melloware, I rebased this branch on the latest v11.
The conflicted file (doc-tabs.tsx) was removed upstream, so the commit was skipped during the rebase.
Please let me know if this PR should be closed or if you’d like me to reapply the fix in the new structure.
Thanks!

Since doc-tabs.tsx was removed upstream and the original fix already exists in master,
This PR no longer applies cleanly to v11.
I’m closing this to avoid noise
