gpui: Set window title on Linux (#7589)

Christian Bergschneider created 2 years ago

Release Notes:
- N/A


Hello everyone,
glad to be contributing to this awesome project! This just fixes a
simple todo!(linux) in gpui.

I also considered setting the window title in the hello world example,
let me know if I should add it in this PR as well.

Best Regards,
Christian Bergschneider
