Release notes do not credit contributors

[twpayne]

Describe the bug

A bunch of people contribute to chezmoi. The release notes do not show these contributions. For example:

• In https://github.com/twpayne/chezmoi/releases/tag/v2.36.0, @catay contributed feat: Add support for Azure Key Vault secrets. #3112 and chore: fix website build by pinning mkdocs version to 1.4.3 #3120, but these are not visible in the release notes.
• There was at least one other case where a contributor (I think a senior staff engineer at Github?) also made a significant contribution and was not credited in the release notes.

To reproduce

Get some excellent contributions and then create a new release.

Expected behavior

Contributors should be properly credited.

Additional context

I'm rebasing commits when merging PRs, but this should not affect anything.

Furthermore, it's not just the contributors that aren't getting credited. The whole PR/commit goes missing.

For example, chezmoi 2.36.0 includes support for Azure Key Vault secrets from #3112, but this is not visible in the release notes.

For info, the latest release with contribution credits seems to be v2.34.3.

Could github-native be partly responsible here?

It also seems to credit based on PR author instead of commit author when it works correctly, which seems incorrect to me.

I'm not sure if git{hub} would be any better.
