Feel free to update the documentation.

Personally, I don't like two names for the same license. This is one of
the reasons why SPFX clearly marks the code license, It is why we have
"SPDX-License-Identifier: GPL-2.0" and not "SPDX-License-Identifier: GPL".

https://spdx.org/licenses/preview/
GNU General Public License v2.0 only 	        GPL-2.0-only
GNU General Public License v2.0 or later 	GPL-2.0-or-later
