ci: always show the installer.log

dscho · dscho · commit bddac8319ed0 · 2023-08-28T14:17:10.000+02:00
We do log the output into a file so that it can be inspected, but
currently the output is not shown unless the installation succeeded.

That's bad. We need the output _particularly_ when the installation
failed.

Let's just print it in a separate step, making sure that it is printed
whenever the installation fails.
