Subversion not installed (svn: not found)

Deploying the Pronamic Pay plugin to wordpress.org failed in https://github.com/pronamic/wp-pronamic-pay/actions/runs/13365922587/job/37323580506 because the svn command was not available:

🔎 Check tag existence
   svn info https://plugins.svn.wordpress.org/pronamic-ideal/tags/9.14.0
   sh: 1: svn: not found
   sh: 1: svn: not found

Subversion has been removed from ubuntu-latest, as mentioned in actions/runner-images#10636:

Removed from the Ubuntu 24.04 image due to maintenance reasons.

Therefore, we need to add an extra step to install Subversion explicitly in this action:

            - name: Install Subversion
              run: |
                sudo apt-get update
                sudo apt-get install -y subversion
