### Updated dependency

FROM ubuntu:24.04@sha256:3f85b7caad41a95462cf5b787d8a04604c8262cdcdf9a472b8c52ef83375fe15

To: whatever dependabot selects
- now it it sha256:3f85b7caad41a95462cf5b787d8a04604c8262cdcdf9a472b8c52ef83375fe15

Maybe there shouldn't be an error if there is no update. No wait, it doesn't fail for Fedora.

### What you expected to see, versus what you actually saw

I saw an internal error (Fedora works fine):

### Smallest manifest that reproduces the issue

_No response_

Reproduce the Docker update with the reported ubuntu:24.04 digest and dependabot.yml configuration. Start at docker/lib/dependabot/docker/file_updater.rb:43 and follow dependency_change_builder.rb:135, comparing the Ubuntu and Fedora paths. Done means the Ubuntu case no longer raises the reported RuntimeError or "No files changed!" failure, with regression coverage for the behavior.
