Upgrade xterm-addon-ligatures for WebGL support

[jacob-israel-turner]

See discussions here for context: https://github.com/vercel/hyper/issues/3607#issuecomment-904832810 https://github.com/xtermjs/xterm.js/pull/3286 https://github.com/xtermjs/xterm.js/pull/2847 https://github.com/vercel/hyper/pull/5888

It should still be noted that there are some known issues with ligatures in WebGL (https://github.com/vercel/hyper/issues/5757 and https://github.com/xtermjs/xterm.js/issues/3303). However, it's my opinion that it's still worth using ligatures in WebGL. But users should know that enabling both may result in some rendering glitches.

@tolbertam let me know if you have a chance to review this! Happy to make any additional changes you want.

As I'm playing with this again, I'm seeing more issues than I thought. Especially while using Vim. The WebGL + Ligature combination appears to be better than what's been released, but people should still be cautious when enabling both.

@tolbertam do you have any interest in merging this PR?

Came looking here when my Hyper + Hyper-Font-Ligatures + Fira Code + macOS Monterrey stopped working after my Monterrey upgrades (on 2 different MacBooks sharing the same .hyper.js configs). Wondering if merging this PR would fix my issue.

@indygwyn mine also stopped working this morning after updating fira code via brew. In the end it seems that using font-firacode-nerd-font (iirc) instead was the true solution.

@jacob-israel-turner Deepest apologies for not noticing this until now. Will try to find some time this week to review this and assuming it looks good i'll merge and release it!

@tolbertam have you had a chance to look at this?

Hey @tolbertam! Unfortunately I've switched from hyperterm to alacritty, so I won't be pursuing this PR anymore. Feel free to close or use whatever is salvageable.
