fix: correct duplicate v19.2.1 entry to v19.2.2 on Versions page

Fixes #8429

The first v19.2.1 entry links to CHANGELOG anchor #1922 (v19.2.2, Dec 11) but was mislabeled as v19.2.1. The second entry correctly links to #1921 (v19.2.1, Dec 3). This matches the pattern of v19.1.3/v19.1.2 and v19.0.2/v19.0.1.
