release: add release workflow environment (#1262)

Migrate applicable secrets to the new 'release' workflow environment and
update appropriate workflows to use these secrets. This is a security
measure to help ensure secrets cannot be accessed by those without
proper permissions.

An example of a passing workflow with these changes can be found
[here](https://github.com/ldennington/git-credential-manager/actions/runs/5007711493).
