Summary

This PR fixes every broken external link found by a repo-wide check: 883 unique URLs across all Markdown files, checked on Oct 26, 2026.

What was broken

• 18 Databricks docs links used the old path style (no /aws/en/ prefix). Databricks has moved those pages, so they returned 404. Each one now points to its current page, matched against the docs sitemap. Every replacement URL returns 200.
• The "Awesome Databricks" link in the README pointed to github.com/devmotion/awesome-databricks. That repo doesn't exist; GitHub's API returns 404. It now points to jrlasak/awesome-databricks (actively maintained, last push 2026-10-22).
• A third-party practice-test vendor page (SkillCertPro) is gone, so the link was removed.

Not changed on purpose

• HTTP 403/429 responses from community.databricks.com, realpython.com, udemy.com and web.archive.org. These sites block automated checks; the pages open normally in a browser.
• Placeholder URLs inside code blocks (github.com/company/..., login.microsoftonline.com/tenant-id). These are illustrative and never rendered as links.
• token.actions.githubusercontent.com, which is the real GitHub OIDC issuer value.

Verification

• markdownlint: 0 errors on the 13 modified files
• Re-ran the external check: only the 403/429 responses and in-code placeholders remain
