Add note about absolute paths to Path::join

[Erk-]

The note already exists on PathBuf::push, but I think it is good to have it on Path::join as well since it can cause issues if you are not careful with your input.

Can you also add an example in the example snippet?

Something like

assert_eq!(Path::new("/etc").join("/bin/sh"), PathBuf::from("/bin/sh"));
