Describe the feature or problem you’d like to solve

As Keep a Changelog described, a good changelog should look like:

## [Unreleased]


## [1.1.1]
### Added
- 1
- 2
### Fixed
- 3
- 4
### Changed
- 5
- 6


## [1.1.0]
...

Now GH CLI uses release note strings or files as the input param (gh release create ${{ github.ref_name }} --notes note-string-here), we need an extra step to parse release notes from changelog files. It would be awesome to support parsing notes by GH officials.

Proposed solution

It would be easier to release on CI, to get rid of any third-party action steps.
