Add static analysis job to find invalid YAML in changelogs

When a changelog has invalid YAML (typically, there is an unquoted @ at the
start of the author field), then the entry will be discarded. This script checks
all unreleased changelogs for validity, and runs as part of the static-analysis
step, so the pipeline will fail if this happens in future.
