Publishing - The `wasm-bindgen` Guide

# Publishing New `wasm-bindgen` Releases

1. Compile the `publish.rs` script:

       rustc publish.rs

2. Bump every crate's minor version:

       # Make sure you are in the root of the wasm-bindgen repo!
       ./publish bump

3. Update CHANGELOG.md to add the to-be-released version number, compare URL and release date. See this example

4. Send a pull request for the version bump.

5. After the pull request's CI is green and it has been merged, publish to cargo:

       # Make sure you are in the root of the wasm-bindgen repo!
       ./publish publish
