actions-runner-controller: Unable to get dockerVolumeMounts working

Hi, I am trying to mount a AWS fsx volume to docker:dind image with the new dockerVolumeMounts feature and I am not sure if it is working as expected.

I puller a docker image from inside one runner and ried to do the same from another runner. The expectation was that it would not pull it again in the 2nd runner but it did.

the nodes are in the same AZ as the FSx volume and all the GHA are running on these nodes.

Chart version: 0.10.5 Controller: v0.18.2
