[document] generate awesome release note

[24seconds]

Description

github's auto generated release note is good. But it could be better.
Gluesql uses this github action. https://github.com/gluesql/gluesql/blob/main/.github/release-drafter-config.yml.

Maybe rust-cli-pomodoro can utilize labels also.

It would be nice to publish cargo too
