PR workflows are treated as deployments by GitHub #104
Description
GitHub is registering Deployments for workflows that run on Pull Requests because they use environment to determine which secret/variable versions to use — dev or prod.
Apparently, GitHub treats anything that uses environment as a deployment. We have something like 550 deployments at this point, even though we've deployed maybe tens of times, at most.
Refactor the non-deployment workflows to instead use repo-scoped variables/secrets that are prefixed or suffixed with the environment name and map to the desired one using variable string templates.
Coordinate with @jayhill to get the secrets migrated.
