[link-checker] Update Microsoft documentation URLs from docs.microsoft.com to learn.microsoft.com #8561

Summary

This PR updates outdated Microsoft documentation URLs that have been migrated from docs.microsoft.com to learn.microsoft.com.

Changes

Fixed 2 broken documentation links:

1. docs/README.md (line 7)

   • Old: `(docs.microsoft.com/redacted)
   • New: `(learn.microsoft.com/redacted)

2. docs/RFCs/007-DataSource-Attribute-VS-ITestDataSource.md (line 10)

   • Old: `(docs.microsoft.com/redacted)
   • New: `(learn.microsoft.com/redacted)

Background

Microsoft has migrated all documentation from docs.microsoft.com to learn.microsoft.com. The old URLs now return 404 errors. These updates ensure users can access the correct API documentation for MSTest.

Link Check Notes

The automated link checker reported 2,810 broken links, but investigation revealed that 2,808 of these were false positives caused by a bug in the link extraction script (it includes the closing ) from markdown [text](url) syntax as part of the URL). Only 2 links were genuinely broken and have been fixed in this PR.

Testing

• Verified the new URLs are accessible and point to the correct API documentation
• Confirmed the markdown syntax is correct in both files
