ci: Use single line args in git-cliff action

[febo]

Problem

Publishing the changelog of a release is currently failing with:

/home/runner/work/_temp/3b272696-5f5f-438d-98f4-f0084559016a.sh: line 2: --include-path: command not found

It seems that since updating the git-cliff action to v4 the multiline argument is being interpreted as multiple commands:

args: |
    "${{ steps.publish.outputs.old_git_tag }}"..main
    --include-path "${{ inputs.crate }}/**"
    --github-repo "${{ github.repository }}"

Solution

Set the args parameter as a single line.

I think this fixes it!
