Publish to PyPI

[arthurbdiniz]

This pull request adds the workflow to publish the CLI to PyPI.

Still need to be tested, but to do that first:

• [x] Account needs to be created at PyPI.
• [x] Username replaced in the commit.
• [x] Add password as a token to Github secrets.

password: ${{ secrets.pypi_password }}
