Use dev GitHub environment for prereleases

[desertaxle]

This PR updates our core release workflows to use the dev GitHub environment when the triggering release was a prerelease. With this change, the nightly release candidates will not need approval before being published to PyPI. This PR also adds a check of the tag before publishing to dev to ensure the new version will be a prerelease in PyPI.
