GitHub Actions now allows developers to use environments without auto-deployment [GA]

### Value Prop

GitHub Environments auto-deploy when added to Actions workflows. This is useful, but also a pain point if you only want to use the environment's variables, not deploy to it. Using environments to store secrets and bind them to a branch is a huge security win, but for others it's more about usability and avoiding deployment spam on a pull request.[/+]

### Expected Outcome

With this release, developers can now use environments without them auto-deploying them. This will be accomplished by adding a boolean option in Actions workflows to note if deployment is true or false.
