fix: republish 2.11.0 as 2.11.1 after a red release gate

The v2.11.0 tag's release pipeline failed at the visual-regression gate
(setup-wizard baselines predating #291) before publishing any artifacts, so
no 2.11.0 build ever shipped. The baselines were regenerated in #292; this
empty commit gives release-please a releasable change so 2.11.1 carries the
full 2.11.0 payload (#288, #290, #291) through a green pipeline.
