Prepare for Python 3.13 support

[remyroy]

See if we can test this on Python 3.13 early or add it to the CI to see if packages are good to go and everything works.

Python is slated for an October 1st, 2024 release date. It's currently available as a prerelease version.

The test_existing_mnemonic_bls_withdrawal test fails.

Failed test:

    def test_existing_mnemonic_bls_withdrawal() -> None:
        # Prepare folder
        my_folder_path = os.path.join(os.getcwd(), 'TESTING_TEMP_FOLDER')
        clean_key_folder(my_folder_path)
        if not os.path.exists(my_folder_path):
            os.mkdir(my_folder_path)
    
        runner = CliRunner()
        inputs = [

Test succeeds when running it again. That is not amazing. Do we have a race condition somewhere?

Monitor https://raw.githubusercontent.com/actions/python-versions/main/versions-manifest.json and check for when Python 3.13 is fully released on or about October 1st, 2024. I just added a calendar reminder.

Once released, we should update our ci-runner to include the proper 3.13 version in the test matrix.

We are now well prepared to support Python 3.13.
