Rename `packages` -> `components`

[azerella]

packages is quite an old name, for a new starter looking at this repo it's immediately more obvious if our components are under a component/ folder.

Along with that, I think that tests should probably be renamed to demo. tests normally suggests tests written in a testing framework.

@HurricaneInteractive It's a good point, I don't know if demo is the right word either though, the folders listed under tests are used for visual testing, not really a preview 🤔

[HurricaneInteractive]

I don't think any of those 3 work.. Is the only current tests for a11y (when you run npm run test)? If that is the case, if additional react/js tests were to be written, a possible solution is to create a top level tests folder could be created. Although that would be kinda annoying because you are separating the component from the tests.

OR in (packages|components)/<component>/src/js you could create react.test.js etc files for your component tests. That way your functionality and tests are contained within the same folder and you still have your visual tests.

The demos are in the design system documentation website. These are just tests for us to see the components in different contexts
