Upgrade keyboard-types to 0.8?

## Feature Request

**What:** The [`keyboard-types` crate](https://crates.io/crates/keyboard-types) started publishing 0.8.x in April 2025. Should Dioxus upgrade to it?

**Consideration:** The `Key` type isn't directly compatible between `keyboard-types` 0.7 ([docs][docs7]) and 0.8.x ([docs][docs8]). Should Dioxus update, or would it be too disruptive to Dioxus' ecosystem?

[docs7]: https://docs.rs/keyboard-types/0.7.0/keyboard_types/enum.Key.html
[docs8]: https://docs.rs/keyboard-types/0.8.3/keyboard_types/enum.Key.html

Start by comparing keyboard-types 0.7 and 0.8.3 through the linked crate documentation, then trace Dioxus uses of the Key type and the dependency. Done means reaching a documented upgrade decision that accounts for compatibility with Dioxus consumers and the required scope of any changes.
