manylinux1's latest is missing a pinned tag

[joerick]

This might just be a random occurrence, but manylinux1's latest tag is pointing to a manifest digest that doesn't have a pinned version (like 2024-04-07-abcabc).

You can see here, the latest tag doesn't point to another build in the list
https://quay.io/repository/pypa/manylinux1_x86_64?tab=tags&tag=latest

whereas here it does point to the most recent pinned release
https://quay.io/repository/pypa/manylinux2010_x86_64?tab=tags&tag=latest

The lack of the tag means we can't pin versions of the images in cibuildwheel. e.g. pypa/cibuildwheel#1778

Looks like it was just a random failure. The latest tag is back
