Adding a new installation method to the README

[curry798]

Hi, we have implemented a lightweight package manager using shell and awk. It helps you download fanyi release packages from the internet and extract them into a unified directory for management, without requiring root permissions.

I mean, can the installation method provided by x-cmd be added to the fanyi README? The installation method for the x command

install fanyi:

x env use fanyi

fanyi demo: x-cmd recorded a demo and article for fanyi bilibili video I apologize in advance if it's not appropriate to raise this topic using a GitHub issue. Looking forward to your reply :) !
