Fix invalid email character in pyproject.toml

[eigendude]

Description

When updating my Pendulum recipe for my OpenEmbedded-based system, an invalid character in the email address caused setuptools to throw an error. The character can simply be removed.

How has this been tested?

Before:

The following error occurs during build time when installing Pendulum with setuptools:

| ValueError: Invalid addr_spec; only 'sebastien@eustace.io' could be parsed from 'sebastien@eustace.io>'

After:

import pendulum succeeds in the installed system.
