feat(cli) Allow Terminus terminal to display emojis (#7093)

### Summary
add Terminus to the list of supported terminal emulators for emoji

### Motivation
Since [Terminus](https://eugeny.github.io/terminus/) is also a xterm.js terminal emulator (same as [Hyper](https://hyper.is/)), and recently [it sets](https://github.com/Eugeny/terminus/commit/e246e22bfd51b1ee5e9e97a391ba6f51230070bb) `TERM_PROGRAM` to `Terminus` (like how Hyper sets it to `Hyper`), it is proper for Yarn to display Emojis also on Terminus.
