Installation problem chain on Ubuntu 22.04.1

[KyleMaas]

node ./index.js wasn't actually doing anything, so I figured I'd try and run the test suite. Got the following error:

/home/ssb-pub/planetary-pub/node_modules/node-bindgen-loader/index.js:62
  throw new Error('No native build was found for ' + target + '\n    loaded from: ' + dir + '\n')

So, to fix this, I went into node_modules/ssb-validate2-rsjs-node and tried to build. This requires Rust. Ubuntu 22.04.1 did not have it by default, so I had to install Rust. Then the build fails because [email protected] doesn't include Cargo.toml. Updating to [email protected] allows it to be built, which then allows tests to run.
