Create GitHub releases automatically on tagging

[kou]

Is your feature request related to a problem or challenge? Please describe what you are trying to do.

GitHub has a feature that manages releases: GitHub releases: https://docs.github.com/en/repositories/releasing-projects-on-github

All GitHub repositories have https://github.com/${ORGANIZATION}/${REPOSITORY}/releases. https://github.com/apache/arrow-rs/releases is for apache/arrow-rs.

Many projects use the feature to show changes in a release, provide artifacts (e.g. source archive) and so on. If we use it like other projects, users may be easy to find changes in each release.

Describe the solution you'd like

We can create GitHub releases from existing our contents. For example, we can use existing CHANGELOG.md for changes in a release.

It's not a big task but it's better that we automate it.

Describe alternatives you've considered

We can do it as a manual task in a release process. For example: https://github.com/apache/arrow-rs/pull/7031/files#diff-7b90af0d72004d8b923b4ed55f67a5f3e40e6a08ec9637f382d6506dd309848dR204

### Create a GitHub release

Run a command such as the following to create a GitHub release from the tag:

```shell
git checkout 4.1.0
gh release create 4.1.0 --title 4.1.0 --notes-file CHANGELOG.md
```

Additional context

Other Arrow projects such as ADBC and arrow-go use GitHub releases:

• https://github.com/apache/arrow-adbc/releases
• https://github.com/apache/arrow-go/releases
