[automated] Update website screenshot expectations

The PP Formula optical-centering shift was 0.19em, which over-corrected
and left every button/badge/nav label about 1.4px low. Reduce it to
0.1em, measured via canvas glyph-ink metrics (~0.09-0.10em centers
uppercase). It is a position:relative nudge only, so no box sizes or
layout change. Verified no regressions across Button, BrandButton,
ButtonPill, Badge, nav, and DownloadLocalButton on 12 pages.
