Update Code Snippet in README

[moshetanzer]

Hi,

Want to make this component as user friendly as possible.

If you use Vue 3 CLI with TS, when you use Vue router variables (to, from) Eslint recognises them as unused vars (this is a Eslint bug). These vars are not unused and work perfectly in production. So just added a line to ignore this unused var error.

Really want this to get out there!

Best Regards
