There is no template with the other Licence files that nbdev supports

I found it while I tested it here. AnswerDotAI/nbdev#1380

TLDR:

https://github.com/fastai/nbdev/blob/96deb7a03bf2cf79a04e1878f67ce099e434e97f/setup.py#L19-L26

licenses = { 
     'apache2': ('Apache Software License 2.0','OSI Approved :: Apache Software License'), 
     'mit': ('MIT License', 'OSI Approved :: MIT License'), 
     'gpl2': ('GNU General Public License v2', 'OSI Approved :: GNU General Public License v2 (GPLv2)'), 
     'gpl3': ('GNU General Public License v3', 'OSI Approved :: GNU General Public License v3 (GPLv3)'), 
     'agpl3': ('GNU Affero General Public License v3', 'OSI Approved :: GNU Affero General Public License (AGPLv3)'), 
     'bsd3': ('BSD License', 'OSI Approved :: BSD License'), 
 } 

and then

nbdev_new --license gpl3

In the settings.ini, the value for licence was gpl3 however the licence file was still apache2
