Updated release workflow (#1060)

## What changes are proposed in this pull request?

Updated the Release workflow. 

- Now it creates an actual release instead of draft
- It also automatically pulls the Next changelog info from the tag and
uses them in the Release notes.

Deleted some unused workflows:

- release-test.yml - run once in feb, 2025

## How is this tested?
