Description
Is your feature request related to a problem? Please describe.
We are not able to catch problems in the build workflows until it's too late. Since our release process requires to cut a new release and the fact that we are distributed that'll adds tons of latency for getting a package out of the building.

Describe the solution you'd like
I'd like to being able to run the release workflows pushing test packages / lambdas / you name it to test instances so we can check that the workflows are working.
Ideally this would be run every time we touch .github/workflows to catch dependabot regressions :)
The emphasis here is running the very same github workflows and not on publishing test artifacts.
Describe alternatives you've considered
None I can think of.
Additional context
In python we have a test package index (https://test.pypi.org/) where we can push things without bothering anyone.
