while i understand that glob is being test here i would recommend removing the link to the issue because i have abranch that tests all that needs to be tested for globbing and i would like to link that issue with that branch. thanks.

Please remove issue link to glob to make sure we are addressing all glob testing in the different branch. WDL looks great and is testing everything that needs to be tested.

Tested on PROOF prod. WDL Workflow fails due to docker error:

FATAL: While making image from oci registry: error fetching image to cache: failed to get checksum for docker://ubuntu:noble-20241118.1@sha256:80dd3c3b9c6cecb9f1667e9290b3bc61b78c2678c02cbdae5f0fea92cc6734ab: unable to parse image name docker://ubuntu:noble-20241118.1@sha256:80dd3c3b9c6cecb9f1667e9290b3bc61b78c2678c02cbdae5f0fea92cc6734ab: Docker references with both a tag and digest are currently not supported

Weird, I'm seeing the same thing on my end, but only with Apptainer, not with Docker. Let me remove the sha tag, we should be specific, but maybe don't have to be that specific...
