chore(deps): bump the pins Renovate does not update (#1330)

Renovate gets no release timestamps for Docker Hub images with more than 1000 tags (https://github.com/renovatebot/renovate/issues/46925) or for quay.io, so the 5-day minimum release age holds them back forever. The e2e workflows, the Kubernetes examples and the toolkit test pins are outside its managers, so these are bumped by hand.

The builder follows the current Alpine instead of the frozen 3.23.
