merge(PR#12): Switch Emacs terminals over to libvterm r/160
This moves the terminals inside of my Emacs from being `gnome-terminal` instances under EXWM over to [emacs-libvterm](https://github.com/akermu/emacs-libvterm).

This incredible package embeds a fully featured terminal emulator (based on `libvterm`) into Emacs with the killer feature of being able to switch a terminal buffer to read-only text mode and use normal Emacs selection commands.

This is something I've wanted for a long time and that `ansi-term` etc. just weren't good enough for!

 ;;; Commentary:
 ;;
 ;; This package adds a function that lets users quickly switch between
-;; different open X11 terminals using ivy.
-;;
-;; It is primarily intended to be used by EXWM users who use graphical
-;; terminals inside of Emacs.
-;;
-;; Users MUST configure the group `term-switcher' and can then bind
-;; `ts/switch-to-terminal' to an appropriate key.
+;; different open vterms via ivy.
