Bug: `create_draft_release.sh` creates changelog from first commit instead of last release

[tanweersalah]

When using the GitHub API to create a release with `"create_draft_release.sh", the auto-generated changelog includes changes from the first commit rather than just from the previous release tag.

Expected Behavior:
The changelog should only include commits made since the previous tag (e.g., v1.1.0 → v0.2.0).

Actual Behavior:
The changelog includes all commits since the first commit, (e.g., v0.0.1 → v0.2.0).

Possible Cause:
The API doesn't allow explicitly specifying the "previous tag", and if release metadata isn't available for the earlier tags (e.g., if releases weren’t created in the UI/API), GitHub defaults to the first commit in the repo.
