Drop deprecated architectures

After home-assistant/docker-base#324 there won't be base image builds
for the deprecated architectures. Techically we could still build an
image here for those architectures by using the last available tag
(`*-2025.11.1`), but since there's currently no need for that, simply
drop them.
