## Describe your changes
Deploy `main` proxies to the preview environments
We don't deploy storage there yet, as it's tricky.
## Issue ticket number and link
https://github.com/neondatabase/cloud/issues/4737
Add 'branch' input to specify commit for deploy scripts/configs. Commit
can't be passed to workflow as ref, and we need to pin configs to
specific commit for main/release deploys
Update deploy input descriptions to match GH interface
Extract deploy jobs from build_and_test.yml to deploy-dev and
deploy-prod workflows.
Add trigger to run this workflows after Neon is build and tested on main and
release branches.
This will allow us to redeploy/rollback/patch config without full
rebuild.
