[PATCH] ci: fix missing Ruby dependency in "documentation" job

From

<20260901-b4-pks-ci-fix-documentation-job-v1-1-a8257ee2a9a4@pks.im>

Our "documentation" job has recently stopped working with the following error:

  + sudo gem install --version 1.5.8 asciidoctor
  + gem install --version 1.5.8 asciidoctor
  ./ci/install-dependencies.sh: 23: gem: not found

The root cause of this is that we never explicitly install Ruby, and consequently gem(1) isn't explicitly pulled inus, either. This used to work alright because we transitively pulled in Ruby via asciidoc. But due to an update it seems that we stopped pulling in the transitive dependency, and consequently we don't have gem(1) available anymore.

Fix this by explicitly installing Ruby.

Hi,

I spotted the failure yesterday. You can see that this fixes the pipeline at [1]. Thanks!
