Resource owned by root user

[track0x1]

I'm building an npm package (in a concourse pipeline) and the task uses a node alpine image. I have a git-resource that points to my source code repo and that is provided to my task as an input. When my task runs ls -la /tmp/build, it shows the temp folder (the repo code) as owned by root and group of root. However, node & npm need to run as a non-root user (user node in the node alpine image).
So now, my node user can't access the repo files and do its thing. How can I get the git-resource to provide the repo with the same user & group?

this is probably the same as concourse/concourse#403

for now, you'll have to chown them yourself and then su node to run the npm tasks
