Update egui to get wgpu on web

[emilk]

We can now run the Rerun viewer on wgpu on the web, thanks to @Wumpf's work in emilk/egui#2107

You need to run cargo install wasm-bindgen-cli --version 0.2.83 after merging this (or scripts/setup_web.sh)

Try it with

 ## Add support for the [`puffin`](https://github.com/EmbarkStudios/puffin) profiler.
 puffin = ["dep:puffin", "dep:puffin_http", "eframe/puffin", "re_log_types/puffin"]

and then

cargo r --features web -- ../data.rrd --web-viewer
