chore(ci): update compare assets processing

[castastrophe]

Description

A lightweight update to:

• Minor eslint updates (move to use warn instead of error to prevent the linter from blocking builds)
• Rename .github/README.md b/c it's using this file for our landing page instead of the root README - https://github.com/adobe/spectrum-css#github-actions-templates-and-bots-oh-my (oops!)
• Update the file-diff output to a more streamlined comment format with a clear summary of changes to components at the top
• Comment-in the scoped stylelint files but leave eslint off for CI at the moment
• Migrate storybook to use project.json for the commands & workflow settings
• Move scripts in package.json from lerna to nx for parallelization (this will fix the caching errors we get when we alernate running lerna & nx for build tasks)
• Standardize licensing and authors for embedded packages to match open source standards (Apache-2.0 & Adobe)

How and where has this been tested?

No regressions for the following commands (tested by @mdt2):

• yarn dev
  • No regression on spinup, css change, or yml change.
• yarn start
  • No regression on spinup, css change, or story change.
• yarn build:preview
  • Tested this by deleting .storybook/storybook-static, then ran yarn build:preview which built storybook-static. Then I ran yarn start and confirmed that what was built is working as expected locally.
• yarn build:components
  • Yep! After cleaning, this rebuilds the dist folders for the components.
• yarn clean:components
  • Removes components dist

To-do list

This is looking really good. The only command I'm not sure about is yarn clean:components. In the console I see The following projects do not have a configuration for any of the provided targets ("clean"), is this expected?

That does not sound right. Let me poke at that. Thanks for checking it!

Alright, this has now been fixed by adding the clean command to each package.json. This will be a relatively short-lived fix since we'll be moving all scripts to be run by project.json & nx.json definitions but it gets us off lerna for running commands since nx & lerna's caches don't play well together.

LGTM! 🎉

I'm a little leery of this, just because we had some problems the last time. Let's move forward with this for now, but keep an eye on it for issues, please!
