Set changelog search util current commit (!49)

## What is the new feature
Make a changelog API that searches for changelogs until the target commit. This way, we can manage the versions more easily.
## How is it implemented
In the GitLab [Changelog API](https://docs.gitlab.com/api/repositories/#generate-changelog-data

), the default `from` attribute is the last tag, which is exactly what we wanted. The default `to` attribute is the latest commit at the default branch. We change it to the target commit where we create the tag.
