Issue #34076: Removing reference to removed path.prefix() function

In the documentation for `std::path::Path`, there is a [reference](https://doc.rust-lang.org/std/path/struct.Path.html#method.is_absolute) to the `path.prefix()` function which has since been removed. The offending reference is now also removed.

First pull request, feedback welcome!
