By including *.scss in sideEffects, we guarantee that imports of our SCSS files aren't getting tree shaken.  This manifested as a problem in the example app, where the example/index.scss file wasn't showing up in the dev server.  The import was getting tree shook (?) because it wasn't importing any specific export.

1. Adding a port to the .env.development file
2. Improving language on the ExamplePage.
3. Removing some CSS that shouldn't have made it in.
4. Adding an LTR direction to index.html
5. Removing plugin1.html, which was a test and shouldn't have been checked in.

This commit adds a variety of plugin classes for both host applications and plugin apps themselves.

This adds an "example-plugin-app" and also gives "example" its own package.json and build files.  It separates out the test apps from the library in their parent directory, making them more independent.

This was just a scratch file where I was taking notes and shouldn't have been checked in.

Doing conflict resolution in package-lock.json is nearly impossible.  Instead of trying, I ran `npm i` to install dependencies and let it fix package-lock.json itself.  This is that generated file.

They needed to be re-created because of the node 16/18 upgrade.  They were in the old format.

…n files

Because this was an old branch we’re resurrecting, it suffered from some ugly version skew in its package-lock.json files and node_modules.  It was breaking the dev build(s).

This way you can run the example dev servers from the root project directory.

Adjusting dependency arrays and ignoring a ‘forbidden’ prop type warning.

The code removed in this commit existed to load plugins via webpack module federation.  It was never intended to be included in this version of plugins.  We don’t intend to use module federation, and are instead investing in a micro-frontend framework like Piral.

Each app can have its own env.config.js because they’re independently run.  We no longer need any of the .env files here.  Since we’re no longer using .env as an input into the webpack process, we need to hardcode the port for the plugins app to 8081 so it doesn’t fall back to 8080 and conflict with the main example app.

This reverts commit 0e40872.
