apt-key is deprecated on Ubuntu Jammy

[li5lo]

Instructions from here:

$ wget -q -O - https://repo.i2pd.xyz/r4sas.gpg | sudo apt-key add -
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
OK

It works but i now get a warning everytime i run sudo apt update.

[r4sas]

I know about that warning, but if it works do we need change anything? ;) I'll try switch to trusted.gpg.d in future.
