Format existing code files and exclude playground/vendor

[sejas]

What?

On #154 we added the playground plugin with multiple vendor files that npx nx format was formatting after each push.

This PR format existing code files and excludes those in vendor.

• Format code files.
• Excludes packages/vendor/* files to be formatted
• Excludes .nx/cahce from git
• Moves package/playground/phpcs.xml to the root directory

Why?

It's better to keep consistency with formatting tools.

How?

I executed npx nx format.

Testing Instructions

• Tests should pass

I was running into this when working on #161 this morning.

Is there a reason we don't run a linter in CI?

Thanks @sejas!

@sejas should we move the packages/playground/phpcs.xml file to the root folder?

Yes, I think it makes sense to have a unique phpcs.xml at the root directory. I moved it here 7073a53
Although, I tried to make it work and phpcs is returning. ERROR: No sniffs were registered.
When I used the whole WordPress phpcs.xml it worked well. We should check if we need to modify the phpcs configuration or the issue only happens on my end.

Is there a reason we don't run a linter in CI?

The project is not 100% well configured and the linter doesn't throw any error, but prettier format the files.
You can try it by breaking the format in any .js file and then running npm run lint, you will see 0 errors, but npx nx format will format the files.
I'll need more time to fix the linter to make it work properly and then, yes! it would be great to add it to CI GH Actions.
Another possible workaround would be adding husky pre-push hook to format the files.

I also added .nx/cahce to .gitignore 0817071. These files weren't created before.
