Create a queue worker for the backup script

[rija]

User Story

As a curator
I want the dataset files I'm publishing to Wasabi to be also backed up to S3 Glacier
So that I have piece of mind that any dataset files we publish has a backup available

Acceptance Criteria

Given a dataset being curated has files associated with it
When the dataset upload status is changed to "Published"
And a message is sent to trigger asynchronously the backup of all the files from EFS
Then a worker script can pick up the message
And calls the backup script

Additional infos

this should make use of the same script as in #2075, make sure the acceoptance criteria for that ticket are still passing.
