ci: format all YAML with `yq`

`yq` is the YAML query tool, used for manipulating YAML files. This
change uses the following command to read in and to pretty-print every
YAML file in this repository:

    for x in $(find . -name '*.yaml'); do
        yq -i -P -oy $x
    done

This makes it a bit easier to automate synchronisation between staging
and upstream, as yq always pretty-prints the entire document when
manipulating files.
