Expected behavior

I would like the formatting to remain consistent. Preferably, the horizontal line separator (---) should be omitted entirely, since the ## headers already provide clear separation between versions.

Actual behavior (suspected bug)

When generating the changelog using cz changelog, there are horizontal line separators (---) between different versions:

## Unreleased

### 📖 Documentation

- **gitlab artifact**: download without s3 access *(Fu Hanxi - ea39918)*
- update readme. add key features *(Fu Hanxi - 9442434)*
- reorganize cli guide. add global cli commands and options *(Fu Hanxi - 33de0a6)*
- more related links *(Fu Hanxi - 428a70a)*

## v0.2.0 (2025-07-08)

### 🐛 Bug Fixes

However, after running cz bump, the horizontal line separator is removed:

## v0.2.1 (2025-07-09)
