Author field missing name

Packages like https://oven.fming.dev/package/pepotron are missing an author:

It's present at https://pypi.org/project/pepotron/

The metadata has `Author` name but not `Author-email`: https://inspector.pypi.io/project/pepotron/1.2.0/packages/b0/80/84d3cb43037597546bc286d36f359efe2208086c298427a017f085a405e3/pepotron-1.2.0-py3-none-any.whl/pepotron-1.2.0.dist-info/METADATA

---

This package only shows the email address:

But https://pypi.org/project/ghapi/ shows the name linked to the email:

The metadata has both Author and Author-email:

https://inspector.pypi.io/project/ghapi/1.0.5/packages/71/6c/2913287a13bc1a5233836d66c3efd6d7bd7d6625fb37c31d36429dec44a4/ghapi-1.0.5-py3-none-any.whl/ghapi-1.0.5.dist-info/METADATA

Start by tracing how package metadata is read and rendered on the package page, using pepotron and ghapi as comparison cases. Check how Author and Author-email are handled; done when packages with both fields show the author name linked to the email, while packages with only an email retain the available information.
