Subject: [PATCH] Fix hello_world_par example on Linux (#4684)

This example does not use the default features from eframe in order to
avoid accesskit, which panics when run from multiple threads, so it must
manually enable the other default features in order to compile correctly
on Linux.

* Closes <https://github.com/emilk/egui/issues/4682>
