Ghostty 1.2.2

Ghostty 1.2.2 is a hotfix to fix a critical regression from 1.2.1 where we accidentally forgot to backport a memory leak fix. As a result, Ghostty 1.2.1 has a significant memory leak under certain scenarios that can cause runaway memory growth. This issue affects all platforms.

We've also included a very small fix for macOS font rendering that would cause very small (one pixel or half pixel) offsets for some glyphs that could result in blurriness.

This was released very shortly after 1.2.1, please see the 1.2.1 release notes.
