chore: Introduce release notes formatting + preview release action (#7247)

### What
- Add changelog formatting file to automate pull request categorization in release notes*
- Add action to trigger preview releases
- Remove unused staging deployment action

**Add changelog formatting file to automate pull request categorization in release notes**

In order for this work, we need to be more strict about our labels usage. More specifically, we need to add one of the four different labels noted in the `release.yml` file. The labels should be self-explanatory. If your PR introduces both features and bugs, you should choose the label based on importance of the changes.
