Access a filename in a gcs bucket seems broken

[professor]

Context, I need to modify an existing pipeline to grab the specific version of a file, in this case kubo-pipeline-store/dev-builds/kubo-deployment-0.37.0-dev.5.tgz

After looking at the readme for IN, I thought this would work:

- name: kubo-deployment
  type: gcs
  source:
    json_key: ((gcs-json-key))
    bucket: kubo-pipeline-store
    filename: dev-builds/kubo-deployment-0.37.0-dev.5.tgz

However, it did not. Here is my work-around:

- name: kubo-deployment
  type: gcs
  source:
    json_key: ((gcs-json-key))
    bucket: kubo-pipeline-store
    regexp: dev-builds/kubo-deployment-(.*).tgz
    version: 0.37.0-dev.5

Because of #20 bug, my work around didn't work. This work around does though....

- name: kubo-deployment
  type: gcs
  source:
    json_key: ((gcs-json-key))
    bucket: kubo-pipeline-store
    regexp: dev-builds/kubo-deployment-(0.37.0-dev.5).tgz
