Update imgui

[codecat]

Hey there, was hoping to get an imgui update in hello_imgui to fix an issue I was having: ocornut/imgui#3982

I'm not sure how often imgui generally gets updated for hello_imgui, so figured I'd just ask. Thanks! 🥰

Hello, the imgui submodule is a direct checkout of imgui's docking branch; so that updating is generally a simple update of the submodule. I did it right now ;-) (see 36237f7)

I'm not sure how often imgui generally gets updated

Hum, when I think of it; i.e once every 2 or 3 months ;-)
But you can also propose PRs, the CI should catch compilation errors.

Good to know! Thanks for the quick update! :D
