Updated GPG Key Install on Ubuntu and Debian

[TahomaSoft]

In Debian and Ubuntu, apt-key is being deprecated and planned EOL in Ubuntu is with Version 22.04 LTS.

So step (2) below (from he.fi/aprsc/INSTALLING.HTML) currently gives a warning and at some point will fail:

1. gpg --keyserver keyserver.ubuntu.com --recv C51AA22389B5B74C3896EF3CA72A581E657A2B8D
2. gpg --export C51AA22389B5B74C3896EF3CA72A581E657A2B8D | sudo apt-key add -

Instead, step (2) should be something like: 2) sudo gpg --export C51AA22389B5B74C3896EF3CA72A581E657A2B8D > /etc/apt/trusted.gpg.d/aprsc.key.gpg

@daskalovst Please follow the installation instructions at https://github.com/hessu/aprsc/blob/main/doc/INSTALLING.md - please read them a bit more carefully, there are a few words about the DISTRIBUTION keyword in there. :)

https://github.com/hessu/aprsc/pull/86 should finally fix this.

Thank you Hessu! Will take a look.
