wrong gpg key for nginx-stable repo

[nadkamo@…]

Hi

gpg key is invalid for nginx stable repo. It works only for nginx-mainline.

Hello!

Can you please elaborate on what is different between stable and mainline as the information provided does not specify it?

It also seems that on SLES 15 the GPG2 command does not provide useful output to make a decision whether the key is the correct one - I'll need to change the documentation to fix that.
