ci(release): replace standard-version with semantic-release (#1666)

[`standard-version`](https://github.com/conventional-changelog/standard-version/) has been deprecated since May 2022, so it is necessary to stop using it for this project.

[**`semantic-release`**](https://github.com/semantic-release/semantic-release) is available as a more capable alternative to help automate the release process:

1. Updating Node/Gem version numbers
2. Generating changelogs
3. Automating GitHub Releases
4. Building Chirpy-gem and pushing it to RubyGems.org
5. Create commits and tags on the `production` branch
6. Merge the `production` branch into the `master` branch

> ⚠️ Note: Step _6_ may be canceled in CD environments due to merge conflicts, so we need to do this step manually in such cases.

Whenever a commit is pushed to the release branch (`production`), all of the above release processes will be triggered.
