OS detection for Rocky Linux missing

[mgkurtz]

Dear folks,

on a Rocky Linux server, I only get a tux (\uf17c) as os_icon, instead of a rocky linux symbol (\uf32b in Nerdfonts).

❯ typeset -pm 'POWERLEVEL9K_MODE|_p9k_os*'; cat /etc/os-release
typeset _p9k_os=Linux
typeset _p9k_os_icon=
typeset POWERLEVEL9K_MODE=nerdfont-complete
