Create a new PR if a previous release PR exists but has been closed

[pwtyler]

Currently, when "Release PR" runs, it checks if a PR exists and otherwise skips the creation step. We should create a new PR if a release PR has been created but then closed.

what are the use cases of this? when would we want a new release PR and not just rebase the PR from the base branch?

The case here is if a pre-release PR was created and then closed. It is my current thought that a new PR should be created, but it could be argued that the existing PR should be re-opened.
