S3 upload action doesn't produce URL with artifact location

[mwasilew]

meta-qcom uses this version of action
https://github.com/qualcomm-linux/upload-private-artifact-action/blob/7c7f53cce0859ed78bc0b905e6ea2cc89ccccd22/action.yml
There is no outputs keyword defined. The action doesn't produce any URL for the upload location. For this reason it's not possible to use the uploaded artifacts in the following workflow actions. This is blocking transition from GCP to S3.
