Maintenance: update layers workflow to properly manage artifacts

[dreamorosi]

Summary

After updating the github/upload-artifact action we need to make changes to the workflow that deploys the Lambda Layers so that it handles the artifact used to identify the layer ARN properly.

In order to add the ARN to the docs we upload an GitHub artifact containing a text file. We do this both in the beta and prod workflow.

Why is this needed?

In a previous version of the GH Action artifacts were treated as mutable, but in this version are immutable so we need to explicitly configure the action to overwrite the previous version since by the time the production workflow runs there's already an artifact created by the beta run.

Which area does this relate to?

Automation

Solution

See action migration steps
