Advertising the Quick Terminal on the Website

[00-kat]

Currently, the Quick Terminal is rather difficult to find, with the only mention I remember seeing being the keybinding actions documentation. I suggest adding a page to https://ghostty.org/docs/features to improve the visibility of this arguably groundbreaking feature, one which many users expect when coming from other terminal emulators such as iTerm2.

If I were to hazard a guess why it wasn't advertised more it was because it was a macOS-only feature. With support for it coming to Linux in 1.2 I think that's a great opportunity to advertise it more
