Remove dependency home (#8307)

Replaces `home::home_dir` with `std::env::home_dir` as these functions
do the exact same thing

<!--
Please read the "Making a PR" section of
[`CONTRIBUTING.md`](https://github.com/emilk/egui/blob/main/CONTRIBUTING.md)
before opening a Pull Request!

* Keep your PR:s small and focused.
* The PR title is what ends up in the changelog, so make it descriptive!
* If applicable, add a screenshot or gif.
* If it is a non-trivial addition, consider adding a demo for it to
`egui_demo_lib`, or a new example.
* Do NOT open PR:s from your `master` branch, as that makes it hard for
maintainers to test and add commits to your PR.
* Remember to run `cargo fmt` and `cargo clippy`.
* Open the PR as a draft until you have self-reviewed it and run
`./scripts/check.sh`.
* When you have addressed a PR comment, mark it as resolved.

Please be patient! I will review your PR, but my time is limited!

Removes dependency home from eframe by replacing `home::home_dir` with
`std::env::home_dir`. `home` was probably originally used since
`std::env::home_dir` was once deprecated because of a bug. Post Rust
version 1.87 this has been fixed and now these two functions do exactly
the same thing.

* [X] I have followed the instructions in the PR template
