Upgrade wasm-bindgen v0.2.88 to 0.2.93

[hobson]

The latest Nov 2, 2024 target wasm-unknown-unknown binary for the itehax-website crate was built wasm-bindgen version 0.2.93 and the 0.2.88 requirement in Cargo.toml will upgrade wasm-bindgen to 0.2.95 making it incompatible with the current version of the target WASM binary for leptos.
So I needed to add the precise pinned version of wasm-bindgen to Cargo.toml and do a cargo clean before cargo leptos watch would stop displaying this wasm-bindgen error message. The message should also add instructions for fixing/pinning your Cargo.toml version of wasm-bindgen:

       it looks like the Rust project used to create this wasm file was linked against
       version of wasm-bindgen that uses a different bindgen format than this binary:
       
         rust wasm file schema version: 0.2.95
            this binary schema version: 0.2.93
       
       Currently the bindgen format is unstable enough that these two schema versions
       must exactly match. You can accomplish this by either updating this binary or
       the wasm-bindgen dependency in the Rust project.
       
       You should be able to update the wasm-bindgen dependency with:
       
           cargo update -p wasm-bindgen --precise 0.2.93
       
       don't forget to recompile your wasm file! Alternatively, you can update the
       binary with:
       
           cargo install -f wasm-bindgen-cli --version 0.2.95
       
       if this warning fails to go away though and you're not sure what to do feel free
