Merge studio web into the monorepo itself

[joanise]

I think this is ready to become our new main branch, as is.

Please review but do not merge: I want to do a fast-forward merge from the CLI, any other way to merge this particular PR risks creating an absolute mess of the repo.

Done:

• replaced the Studio-Web submodule by the packages/studio-web subdirectory
• merged the histories so we have a trace of both original repos - this repo now has two unrelated initial commits, I hope that doesn't get to confusing
• CI works from the monorepo
• commitlint activated globally
• Aidan already had the studio-web published from the monorepo with the submodule, so that should keep working with the subdirectory
• running tests is now uniform and well documented

Still TODO (and I think it's OK to do these after merging the PR):

• fix the publication of studio-web to npm from here instead of from the Studio-Web repo (n/a, Studio-Web is deployed, not published)
• activate pretty-quick auto formatting -- eventually -- I still think it's too early to do it because we have branches to rebase and merge and applying pretty-quick everywhere now will make that impossible
• the top level needs a LICENSE file and we need to figure out the correct Copyright statement to put there.

@roedoejet and @dhdaines if you can review this, that would be great, and then I'd like to forward-forward merge this into main soon so future development will continue from here.

Basic build and run works well for me - we may wish to include a note to remove packages/Studio-Web when updating for people with case-sensitive filesystems, since testing will break otherwise.

getting a lot of these when running nx test:once web-component:

     AssertionError: Timed out retrying after 4000ms: Expected the subject to host a shadow root, but never found it.

I get those errors if I don't first launch nx serve web-component in a separate window.

Unfortunately, no, I still don't have a single-call command to test web-component... (Well, we do, there's a "test" script in packages/web-component/package.json, but it's broken at the moment.)

Ah, okay, yes, I have to serve the test data and the web-component (and remember to killall node before so it gets the right port number). Now it works.

This works at least as well as it did before, I approve

Awesome @joanise !

To document the general approach used in merging:

In a fresh Studio-Web clone:

git checkout -b dev.move-to-monorepo
mkdir packages/Studio-Web
git mv -k * packages/Studio-Web
git mv -k .github .gitignore .husky .prettierignore packages/Studio-Web

make sure the only changes are a long list of renamed: files. And make sure there are no files left.

git commit -a -m'refactor: move all Studio-Web files to their future monorepo location'

Go to Web-Component on branch

git checkout -b dev.merge-studio-web
git remote add sw git@github.com:ReadAlongs/Studio-Web.git
get fetch sw
git merge --allow-unrelated-histories sw/dev.dev.move-to-monorepo

A bunch more adjustments were required, but those are all in separate commits, so see the commit logs for more details.
