GPUI introduces GPL-3.0 crates

[PRRPCHT]

Hi there,

I may have found a license issue. I've just switched from using GPUI and gpui-component from the versions published on crates.io to the main branches on their respective repos. My CI runs cargo deny and raised a problem: when using GPUI from the repo, it introduces in the project's dependencies 3 GPL-3.0-or-later crates: ztracing, ztracing-macroand zlog. Of course Apache-2.0 and GPL-3.0-or-later are not really compatible...

I've already started a discussion on the Zed repo, but I also wanted to raise a flag here.
