Fields are missing when I `pip show` my Python package

I recently uploaded my first Python package to PyPI. The relevant parts of pyproject.toml are defined as follows (full file available here):

[build-system]
requires = ["setuptools>=61.0"]
build-backend = "setuptools.build_meta"

[project]
name = "jutility"
version = "0.0.4"
license = {text = "MIT License"}
authors = [
    {name = "Jake Levi", email = "jakelevi@hotmail.co.uk"},
]

# ...

[project.urls]
homepage = "https://github.com/jakelevi1996/jutility"

After installing this package with the command python3 -m pip install -U jutility, I run the command python3 -m pip show jutility, and get the following output:

Name: jutility
Version: 0.0.4
Summary: Collection of Python utilities intended to be useful for machine learning research and experiments
Home-page: 
Author: 
Author-email: Jake Levi <jakelevi@hotmail.co.uk>
License: MIT License
Location: /usr/local/lib/python3.10/dist-packages
Requires: matplotlib, numpy, Pillow
Required-by: 

Notably, the Home-page and Author fields are empty in the output from pip show, although they seem to be defined in pyproject.toml.

How should I change pyproject.toml to make these fields display properly in the pip show output?

Version-wise, I built and uploaded these packages to PyPI on my Windows 10 PC with Python 3.7.6, but I also tried downloading and installing this package and displaying the pip show output from a Google Colab notebook with Python 3.10.11. The package works completely as expected in the Colab notebook, but I get the same pip show output with empty Home-page and Author fields. I'd just like to know what I need to change in order to get these fields to display properly.

There is a simple solution to populating the Author field in pip show mypackage, using only pyproject.toml (IE without having to make a separate setup.cfg file). The clue is in the full pyproject.toml specification, specifically in the authors/maintainers section:

1. If only name is provided, the value goes in Author or Maintainer as appropriate.
2. If only email is provided, the value goes in Author-email or Maintainer-email as appropriate.
3. If both email and name are provided, the value goes in Author-email or Maintainer-email as appropriate, with the format {name} <{email}>.
4. Multiple values should be separated by commas.

It follows that the the following pyproject.toml configuration should populate Author field with just the author-name, and populate the Author-email field with just the email address:

[build-system]
requires = ["setuptools>=61.0"]
build-backend = "setuptools.build_meta"

[project]
...
authors = [
  {name = "First McLast"},
  {email = "firstymclast@example.com"},
]
...

IE name and email are in separate brackets.

Result (Python 3.10.12, setuptools=76.0.0, pip==25.0.1):

$ python -m pip install -e .; python -m pip show mypackage
...
Author: First McLast
Author-email: firstymclast@example.com
...

Also, the Home-page field now also appears to be populated. Maybe this is just something that was fixed in a more recent version of Python 3.10.12/setuptools/pip/etc.
