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.

I fixed the issue by deleting all but the first 3 lines of pyproject.toml, so that pyproject.toml looks like this:

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

I then added the following configuration to setup.cfg (thank you to @Ratul Hasan for the suggestion):

[metadata]
name = jutility
version = 0.0.8
author = Jake Levi
author_email = jakelevi@hotmail.co.uk
description = Collection of Python utilities intended to be useful for machine learning research and experiments
long_description = file: README.md
long_description_content_type = text/markdown
license = MIT License
license_files = LICENSE
url = https://github.com/jakelevi1996/jutility
project_urls =
    Documentation   = https://github.com/jakelevi1996/jutility
    Source Code     = https://github.com/jakelevi1996/jutility
    Bug Tracker     = https://github.com/jakelevi1996/jutility/issues

[options]
python_requires = >=3.7
install_requires =
    matplotlib>=3.5.3
    numpy>=1.21.6
    Pillow>=9.5.0

I now get the following output from python3 -m pip show jutility, as desired:

Name: jutility
Version: 0.0.8

More information on setup.cfg files is given on the page Configuring setuptools using setup.cfg files. It remains to be seen why setup.cfg files are not mentioned in the Packaging Python Projects tutorial, but this is a question for someone else.
