docs: Fix Tink repository link

[owlcdr]

What changed? Why?

Updated the Tink repository link from github.com/google/tink to github.com/tink-crypto/tink since the project has moved. This ensures users land on the correct, actively maintained repo and avoids confusion from dead links.

• No functional changes—just a documentation fix.
• Confirmed the new link resolves correctly.
