CHANGELOG can be automatically added to the description of a release.

Description of the new feature/enhancement

Give a new option to choose whether add CHANGELOG to the description of a release automatically.

Proposed technical implementation details (optional)

According to tag's name and release name, the CHANGELOG which belongs to that release can be automatically added to the end of the release description. And if the same content is already here, then it won't do anything.

Plan to use PyGithub to achieve this.

This feature can depend on the hide-info feature, so that the changelog info will be surrounded by the hide block
