Wrong LGPL version detection

[stefan6419846]

Description

https://github.com/cackharot/suds-py3/blob/master/suds/xsd/sxbuiltin.py is being wrongly detected as being (LGPL-2.1-or-later AND LGPL-2.0-or-later) AND LGPL-2.0-or-later, although it explicitly states:

This program is free software; you can redistribute it and/or modify it under the terms of the (LGPL) GNU Lesser General Public License as published by the Free Software Foundation; either version 3 of the License, or (at your option) any later version.

Id est, I would expect the results to at least contain a reference to LGPL-3.0, but they do not.

How To Reproduce

• wget https://github.com/cackharot/suds-py3/raw/1d92cc6297efee31bfd94b50b99c431505d7de21/suds/xsd/sxbuiltin.py
• scancode -l --license-text --license-text-diagnostics --yaml error.yml sxbuiltin.py
• cat error.yml

Result
