[📃 Docs]: broken documentation link for Microsoft Planner provider

[gecube]

Summary

In the list of available providers in the documentation, Microsoft Planner is shown as a supported provider.
However, clicking its documentation link leads to a non-existent page:

❌ https://docs.keephq.dev/providers/documentation/microsoft-planner-provider → returns 404 Not Found

---

🧩 Steps to reproduce

1. Open the documentation page listing all providers
   → https://docs.keephq.dev/providers/overview
2. Scroll to Microsoft Planner provider
3. Click the Documentation link
4. Observe that the page does not exist and returns HTTP 404

---

💡 Expected behavior

• The link should open a valid documentation page describing:
  • How to configure and authenticate Microsoft Planner integration
  • Required permissions and scopes
  • Example YAML / UI configuration

If the provider is not yet implemented, the link should be hidden or lead to a “Coming soon” placeholder page instead of a 404 error.

---

✅ Proposed fix

1. Either add the missing documentation page at
   /providers/documentation/microsoft-planner-provider,
   or
2. Temporarily remove / disable the link from the provider overview list until the page exists.

---

🧠 Rationale

Broken documentation links:

• Confuse users looking for integration setup instructions
• Create impression of incomplete or unstable documentation
• Are easily fixable by either adding a stub page or removing the link

The broken documentation link for the Microsoft Planner provider is due to a mismatch in the URL. The correct documentation is available at /providers/documentation/planner-provider, which covers setup, authentication, permissions, and workflow examples. The link should be updated to point to this page instead of the non-existent /providers/documentation/microsoft-planner-provider to resolve the 404 error and provide users with the necessary integration guidance citation.

To reply, just mention @dosu.
