Update extract-image-names.sh for [email protected]

[danielhollas]

This is a follow-up on #491. The jq script in extract-image-names.sh started failing with [email protected] since the metadata output of buildx changed. We need to change the jq invocation accordingly before we're able to update the action.

This is the error from https://github.com/aiidalab/aiidalab-docker-stack/actions/runs/10287638235/job/28471150939

jq: error (at bake_metadata.json:691): Cannot index array with string "image.name"

Thanks for the fixing, looks all good. (sorry, I open 3 tabs about this issue and didn't go to the correct PR one to make the comment)

Thanks for taking a look. I've updated the issue with the concrete jq error that I saw.
