Subject: [PATCH] feat(action): add an output for the changelog content (#4)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* feat: add an output for the changelog content

::set-output is
[deprecated](https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/)
in favor of [environment
files](https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions#environment-files).
This has better multiline support, so add the contents of the changelog as an output for cases where
you are creating a GitHub release.

BREAKING CHANGE: self-hosted runners will need to be at 2.297.0 or greater

* fix: update multiline output usage

https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions#multiline-strings

* docs(readme): add content as output
