uefi-raw: net: implement Display for Ipv4Address and Ipv6Address

Author: phip1611

uefi-raw/CHANGELOG.md

@@ -8,6 +8,8 @@
 - Added `::octets()` for `Ipv4Address`, `Ipv6Address`, and
   `MacAddress` to streamline the API with `core::net`.
 - Added `::ZERO` constant for `IpAddress`
+- `Ipv4Address` and `Ipv6Address` now implement `Display`. They
+  use the same formatting as `core::net::{Ipv4Addr, Ipv6Addr}`
 
 ## Changed
 - **Breaking:** The MSRV is now 1.85.1 and the crate uses the Rust 2024 edition.
