v1.3.0

• Add a warning to help users who accidentally end up in the "running on the Bitbucket instance" flow in bbs2gh migrate-repo
• Fix version check so that a version later than the latest version published on GitHub isn't considered old
• Fix download-logs commands suggested by bbs2gh migrate-repo and ado2gh migrate-repo to use correct arguments
• Fix version number exposed in headers and generate-script scripts, removing the revision component so it matches the published version
