The "GPL-2.0-only" and "GPL-2.0-or-later" are license short identifiers.
They do not belong to the SPDX spec, but rather on the license list.
They were introduced in the SPDX License List v3.0 (current version is 3.5):
https://spdx.org/licenses/ 

It seems the examples in the kernel documentation use identifiers
from earlier versions of the license list.

These are still valid identifiers (albeit deprecated), 
so there is no urgent need to have them replaced.
