"'/src' is owned by someone else" reported when building status.jenkins.io with docker-hugo

[MarkEWaite]

We are happy users of the docker-hugo container image to build the https://status.jenkins.io showing the condition of Jenkins infrastructure. We manage that site at https://github.com/jenkins-infra/status and are currently using docker-hugo 0.95.0.

We'd like to upgrade from 0.95.0 to 0.111.3 but our upgrade attempts fail due to an error message from command line git inside the container image. The error message reported by the GitHub action and in local development is:

mwaite@debian11-a:~/hub/infra/status$ docker compose up --build --force-recreate

Can you suggest changes that we should make in order to allow our site build process to upgrade?

The failing pull request is:

• https://github.com/jenkins-infra/status/pull/305

I assume we could create our own container derived from your container with the addition of a RUN git config --global --add safe.directory /src, but I wonder if there is a better way or an easier way.
