v1.1.1

• Upgrade dependencies. This includes an update to @actions/core that gets rid of a deprecation warning when the action runs (#45).

There are still problems running the action on the ubuntu-22.04 image, as mentioned in #42. Until that is resolved, it's recommended to use the action with the ubuntu-20.04 or ubuntu-18.04 images. Note that this doesn't prevent you from building snaps targeting core22: the build will still occur within an appropriate LXD container.
