Set up gpg-agent in .bashrc

I could not get the gpg-agent of home-gpg-agent-service-type to
recognize a YubiKey, which failed with:
scdaemon[19539]: pcsc_establish_context failed: service stopped (0x8010001e)

Let's use the commands from here instead:
https://github.com/drduh/YubiKey-Guide?tab=readme-ov-file#replace-agents

gpg is installed system-wide, not in Guix.
