Features - list which issues' changes are going to be included in the next release

[whorka]

Feature Description

A way to list which issues' changes are going to be included in the next release.

Proposed Solution

In the github action that creates the release candidate find all the issues that have been closed since the previous release and tag them as "release candidate".

Also update the release issue template to describe how to find them in order to determine if a release is a patch|minor|major.

When a release is created, the "release candidate" tag should be removed from all issues.
