When using the markdown code block embedded in the PR body to supply a
changelog, we were discarding any blocks that were empty.
This prevents the use of a release-note:none empty block, which is
useful for signaling that you're intentionally not including a release
note for a PR, as it has no user-facing change.
This PR updates to add support for that, and a test to ensure it works
correctly.
