Nightly icon is showing in release builds

Thanks for filing an ! Please answer the questions below so I can help you.

• iTerm2 version: 3.6.0
• OS version: Sequoia 15.6.1

At my job we have both brew and direct installs using a new icon that appears to be the formerly used for nightly builds.

Detailed steps to reproduce the problem: This reproduces 100% of the time at launch. It shows the icon with an alpha symbol in all contexts (like the dock and Tab + Command switcher).
