This commit updates all examples to not use `path` dependencies but
rather use versioned dependencies like would typically be found in the
wild. This should hopefully make the examples more copy-pastable and
less alien to onlookers!
The development of the examples remains the same where they continue to
use the `wasm-bindgen`, `js-sys`, `web-sys`, etc from in-tree. The
workspace-level `[patch]` section ensures that they use the in-tree
versions instead of the crates.io versions.
This commit does a few things, including:
* Fixing the generated JS of `wasm-bindgen` to allow polyfills to work.
(a minor tweak of the generated JS)
* All examples are updated to include a Webpack-specific polyfill for
these two types to get examples working in Edge.
* A new page has been added to the guide about supported browsers. This
mentions known caveats like IE 11 requiring `wasm2js` as well as
documenting some `TextEncoder` and `TextDecoder` workarounds for Edge.
Closes#895
