…; add trailing slash to PyPI repository URL (in accordance to PEP-503)
This should solve Issue #23980, by moving the space in front of the
package name and the package name out of the `gitea-origin-url` block.
It also adds a trailing slash to the PyPI repository URL in accordance
to [Python PEP-503](https://peps.python.org/pep-0503/).
