Trigger and wait for a GitHub Action workflow from a Jenkins pipeline.
Given the API to trigger a GitHub Action doesn't return any identifier, the strategy adopted here is to generate a UUID from Jenkins, passing it to a standardised inputs.trigger_id field to the newly triggered GitHub Action.
The identifier is going to be used as a workflow artifact name, which will then be used to identify the actual workflow run from Jenkins.
This will enable Jenkins to wait for the specific workflow run completion.
