Update image crate to 0.25 (#4160)

To not produce duplicating deps in Rerun
(https://github.com/rerun-io/rerun/pull/5280) I suggest we wait with
merging this until these crates have updated to `image` 0.25:
* [x] [`arboard`](https://crates.io/crates/arboard)
* [x] [`gltf`](https://crates.io/crates/gltf)
