Add GitHub Releases to be able to subscribe to them

[o-alexandrov]

Currently, rive-react has Releases, but those releases typically contain useless (empty) information due to most of the changes happening in this repository, which doesn’t have Releases, so no way to subscribe to new versions.

Please introduce the exact same GitHub Releases procedure as you do in rive-react.

• it’s impossible to subscribe to your Changelog.md file changes, except the option to subscribe to all commits, which is not an option due to too much unrelated noise
