docs: Add KnowBe4 data warehouse source documentation

[inkeep]

Summary

This PR adds documentation for the new KnowBe4 data warehouse source that was implemented in PostHog/posthog#73196.

Changes

• Creates contents/docs/cdp/sources/knowbe4.md – new documentation page for the KnowBe4 connector

What's documented

• Overview – KnowBe4 is a security awareness training and phishing simulation platform
• Prerequisites – Admin access required to generate a Reporting API key under Account Settings > API
• Configuration – Two required fields: API key and region (US, EU, CA, UK, DE options)
• Sync modes – All tables sync as full refresh only (KnowBe4's API doesn't support incremental sync)
• Supported tables (8 total):
  • users – User data with phishing risk scores
  • groups – Group configurations
  • group_members – Group membership relationships
  • phishing_campaigns – Phishing simulation campaigns with aggregate results
  • phishing_security_tests – Individual phishing security tests (PSTs)
  • phishing_security_test_recipients – Per-recipient test results
  • training_campaigns – Security training campaigns
  • training_enrollments – Individual training enrollments
• Troubleshooting – Invalid API keys and region mismatch issues

Notes

• The source is currently in ALPHA status (as set in the backend)
• The sourceId: Knowbe4 matches the backend's ExternalDataSourceType.KNOWBE4
• The docsUrl in the source code already points to /docs/cdp/sources/knowbe4
