remove version pin on tao

[sehnryr]

Version 0.30.3 of tao includes the fix for the window resize issue on Wayland.

Fixes #3314

This is a bit unfortunate - tao is part of our public API and bumping it would be a breaking change (ie 0.6 -> 0.7). A long-term way of fixing this would for dioxus to get onto a 1.0.0 so we could use the minor version for dependency upgrades or removing tao from our public API altogether (which we need to do for winit, eventually).

Is there a way we can address the tao bug without bumping tao?

Alternatively we could yank dioxus-desktop 0.6.0 and 0.6.1 and simply force everyone onto the new, fixed tao, but that would might also require yanking dioxus 0.6.0 / 0.6.1? If we yanked dioxus-desktop then I think the crates resolver would always just choose the new one.
