CASSANDRA-19110 convert deprecated apt-key command to new method on deb systems

[zyxep]

Hi,

I've updated the 2 shell scripts that generates the output for Debian based systems.
since apt-key is deprecated and getting removed soon then I suggest on moving to the "new" way with gpg --dearmor method and pointing the apt source to the new file.

I've pointed the source of the gpg key to /etc/apt/keyrings because /usr/share/keyrings/ is also getting converted.
On Ubuntu 22.04 a default folder /etc/apt/keyrings is created but not on 20.04 hence my comment in that shell script.

There are no output of gpg --dearmor so I have not updated add_repo_keys.result

I've also updated the deb line in get_deb_packages.sh to use signed gpg key since apt is starting to require keys like that.

Hi @zyxep , I am just checking if this has a corresponding JIRA ticket?

Aha I see, this is just about the documentation ...

@driftx does this make sense to you? I think you are more fit to review this.

Ya, only documentation :)
I tried to find _/download docs but wasn't able to find it, maybe it just uses the same shell scripts to compile it's data from.
