Stable, versioned releases

[bignose-debian]

Please create releases of this project. These should be identifiable, persistent, point-in-time tarballs of the source code files, complete with a changelog entry describing the differences from the previous release, and identified by a sensible version string.

These will appear at https://github.com/davazp/graphql-mode/releases so that stable releases can be found without navigating Git tools or GitHub platform.
