Move resources to web which leads to bug

1. Move several files to `web`.
2. Update vite config to point to the current location.

+Reproduces an issue where vite gets confused where external `node_modules` are. 
+
+The project starts from the end of the [ScalaJS vite tutorial](https://www.scala-js.org/doc/tutorial/scalajs-vite.html),
+then:
+1. Stable: Migrate to Slinky's `main` branch that supports React 18 (previous commit).
+2. Buggy: Move several resources to the `web` folder (current commit).
+
+## How to reproduce
+Terminal 1:
+- Run `sbt "~fastLinkJS"`
+
+- Terminal 2:
+- Go to `web`
+- Run `npm install`
+- Run `npm run dev`
+
+## Workaround
+
+While it is running with the bug, run the following at the root:
+```
+cp -r web/node_modules .
+```
