Missing forbid unsafe_code attributes

[YgorSouza]

Some crates have the safety dance badge in their individual README files, but none of them have the required #![forbid(unsafe_code)] attribute. Indeed, some of them display the badge even though they actually have unsafe code, namely eframe and egui-winit, which is misleading. The badge should be removed from crates that have unsafe code, and those that don't should have the attribute so they are parsed correctly by cargo-geiger.

Good catch! I've removed the misleading badges.

As for parsing correctly with cargo-grieger - is that something you'd be willing to contribute?

Sure, I'll try to have a look at it this weekend. As far as I can tell, this is the line that prevents unsafe code:

egui/Cranky.toml

Line 4 in f94187a

deny = ["unsafe_code"]

But it isn't part of the crate source and is only used during CI, so geiger doesn't see it.

So it should only be a matter of adding the attribute to the crates that don't have unsafe.
