Summary

Correct the Unstable C API tier references from PEP 697 to PEP 689 in Doc/whatsnew/3.12.rst, including the associated internal label.

The separate PEP 697 entry remains unchanged.

Closes #161078.

Testing

• Official documentation dependencies installed from Doc/pylock.toml.
• Verified PEP 689 and PEP 697 references.
• Validated all 1,192 local HTML fragment links on the affected page.
