gpu-dawn: fix build instructions

Browse source 
`-Ddawn-from-source=true` was removed as an option when building gpu-dawn
in specific, since after all the project exists only to build Dawn from source.

Other projects (like `mach/gpu`, the WebGPU Zig bindings) of course still continue
to respect `-Ddawn-from-source=true`.

Originally reported as an issue [in Matrix](https://matrix.to/#/!bIJeTLtOHucXQpqIcH:matrix.org/$IiqVW7rz75Du15sNGFGQiDWGqC-MboJUBv8w0XWb828?via=matrix.org&via=mozilla.org&via=pythons.space).

Dawn (specifically all the shader compilers, and the DirectXShaderCompiler) is a large C++ codebase and takes 5-10 minutes to build on a modern laptop, you just need to specify `-Ddawn-from-source=true` and wait. Since waiting is no fun, we also have binary releases produced by our GitHub actions:
