Fix bad spaces in classifiers

The extra spaces caused PyPI upload to fail with the following error from uv:
error: Failed to publish `dist/elapi-2.4.0-py3-none-any.whl` to https://upload.pypi.org/legacy/
  Caused by: Upload failed with status code 400 Bad Request. Server says: 400 'Framework   :: AsyncIO' is not a valid classifier. See https://packaging.python.org/specifications/core-metadata for more information.
