Readme out of sync with library docs

[MarijnS95]

The platform-specific notes in the README are missing a detail about gtk::init(), which is only covered in the library docs: https://docs.rs/wry/latest/wry/#platform-considerations. Perhaps it should also have a specific ### Unix/Linux subsection like the README.

The Android docs appear to have some more overlap though.

Should there be a CI process to keep these in sync to make it easier to find relevant information, regardless of where this is being read?

@amrbashir it still looks to be mostly out of sync. Why don't you use something like #[doc = include_str!("../README.md")] or cargo-readme?

I didn't know about cargo-readme, that's a cool tool

@amrbashir neat, thanks for replacing that so quickly! This not only helps getting and keeping The two files consistent, it also means the example code is (build-)tested against the latest source at all times.
