Use Github Actions for release automation

See this issue comment for basic reasoning why.
TDLR; While it is not CI, it should automate changelog creation and version releasing.

As per elementary's README on their actions, it does require a file debian/control and updates to appdata.xml

Confirmed the necessity to update appdata.xml by Daniel

A release automation workflow is in the repository, but it relies on branch juno to have a pull request to run. The juno branch will be the "stable" branch, and will be updated by pull requesting from master whenever it is time to release a new version. This will require updates to appdata.xml, as mentioned above, but should automate the updates to the debian files, which is a huge help.
