arc.static() with fingerprinted assets doesn't work with typescript

[karlmolina]

Describe the issue
Using fingerprinted static assets, the static.json file isn't deployed with typescript.

Steps to reproduce

1. Checkout https://github.com/karlmolina/arc-typescript-fingerprint-bug/tree/main
2. npm i
3. arc deploy
4. Open the deployed site
5. See that the style.css file does not have a fingerprint suffix.

Expected behavior
The css file should be fingerprinted.

Additional context
I figured that the problem exists because the arc.static() function pulls the static.json file using a readFile and not an import which typescript doesn't know about.

I fixed the problem by making a plugin that copies the static.json file to the .build folder on hydrate.copy. A better workaround might be to rewrite arc.static() since this workaround isn't generalized for multiple lambdas.
See https://github.com/karlmolina/arc-typescript-fingerprint-bug/tree/fix

module.exports = {
  hydrate: {
    copy: async ({ arc, inventory, copy }) => {
      // Copy static.json to build
      const fs = require("fs").promises;
      const path = require("path");
      await fs.cp(
        path.join(process.cwd(), "public", "static.json"),
        path.join(
          process.cwd(),
          ".build",
          "http",
          "get-index",
          "node_modules",
          "@architect",
          "shared",
          "static.json",
        ),
      );
      console.log("Copied static.json to build");
    },
  }
}

After making this issue I found another issue which is basically the same thing architect/functions#536

I've reopened this issue on the plugin-typescript repo as I believe it is still valid.

I think one potential fix here is to incorporate @karlmolina's fix, which copies the static.json into each lambda (see the custom code for that here) into this plugin. This way, no changes to @architect/functions is needed. That would be preferable to me, as it leaves TypeScript-specific concerns out of the generic node.js runtime helper that is functions.

I am doing this as nothing more than issue gardening; I personally have no interest in this plugin and do not use it.
