There are minor differences in this v3 and v2, isn't this version on top
of v2, can those changes be from Stephen?

API (Application Programming Interface) is an acronym and should be all
uppercase, like 'APIs'.

Overall the language in this list is imperative, I think it helps to
make it simple, but I am not sure about the tone, I wonder if we can do
better, do you have any suggestions?

`check-spdx-tag.sh` seems moved in v2 to "additional suggestions", I am
for keeping it here, as "additional suggestions" are more things to take
into consideration during design/development, above are actual scripts
that we can use to verify code.

And long term intention was to move this "tools to run list" to a more
generic documentation, as these are not really specific to new PMD
guide, but "additional suggestions" will stay in this document.
