chore(modules): update modules for spin v0.4.0 compatibility

[vdice]

Updates the bartholomew and spin_static_fs modules for compatibility with spin v0.4.0.

The bartholomew.wasm was built from the most recent v0.4.0 tag and spin_static_fs.wasm from HEAD.

Currently on HEAD, when we run npm run spin with a spin v0.4.0 client, we see:

$ npm run spin

> docs-website-template@0.1.0 spin
> nodemon --watch content --watch static --watch templates --ext md,rhai,hbs,css,js --verbose --legacy-watch --signal SIGINT --exec 'spin up --file spin.toml'

Note that updates will again be needed upon the next spin release, at least for bartholomew (fermyon/bartholomew#109).

Tested via npm run spin with spin spin 0.4.0 (784094e 2022-07-13).
