In #19776 we discovered that basing both the base container *and* the app container off of `.ruby-version` causes a chicken-and-egg problem wherein upgrading Ruby versions requires a few stop-and-gos. Let's make those stops reviewable as separate chunks instead: use a new `.ruby-version-next` for building base images, not the `.ruby-version`, thus allowing GitHub Actions to fire off an automated build (which, when complete, we can take the SHA sum from and use it to open a second PR updating the app image to use it, and `.ruby-version` can be updated to match `.ruby-version-next`).
