Update all examples, all tests, and `egui_demo_app` to use `env_logger 0.11`
- [x] I have followed the instructions in the PR template
This PR updates all examples, all tests, and the egui_demo_app crate to use the latest version of env_logger, 0.11. This helps to clean up the list of outdated crates listed when running cargo outdated --root-deps-only --workspace.
To ensure I didn't break anything, I ran cargo build --all-features --all-targets (and the same with cargo test), and saw nothing that made me feel that I broke anything. Additionally, the CI run for my commit finished successfully: https://github.com/LikeLakers2/egui/actions/runs/10347887485
Before making this PR, I did take notice of a similar PR, https://github.com/emilk/egui/pull/4164, but because it's a 5-month-old draft that appears to be abandoned, I decided to make this PR.
@bircni Thanks! I'm on windows so I couldn't run that shell script - which is why I pointed to the Github Action run, because I was pretty sure it'd run scripts/check.sh. :)
The script is for Linux only 😊
Is there anything blocking this from being merged?
