feat: Add workflow URL to EC2 instance tags

[roberto-civitas]

Add the workflow_url to the instance tags so that it's easier to identify which build is being run by the instance.

The property is passed along from the webhook lambda, as part of the SQS event.

@roberto-civitas thx for the PR. Good idea, but I am afraid it won't work.

Runners are indeed created based on the workflow_job event, however which job starts on the runner is orechestrated by GitHub. So the actual job running on a runner is not alwasy the event that leading to creation of the runner. The module supports XRay which allows you to see correlation between which events is causing runner creation.

Next to het workflow_job event created there is a event for in_progress. This event could be used to tag an instance with the job in progress. It should not hard to correlate based ont he the event since this event contians the runner name as well.

Wondering what your thoughts are.

Thank you for having a look at the PR. I will modify it so that it uses the event you suggest.

Maybe good to have a short discussion on how to implement this. This to avoid you wast time on a proposal that is not fitting. My first thought would be having an extra lambda as part of the control plane. But no time to dig in so far.
