TASK: Workspaces prefer import via `main` index.js instead of `src/foo/bar.js`

[mhsdesign]

Description

instead of

import DropDown from '@neos-project/react-ui-components/src/DropDown';
import Badge from '@neos-project/react-ui-components/src/Badge';

we should write:

import {DropDown, Badge} from '@neos-project/react-ui-components';

this way our code is cleaner / and we use the same api as the neos-extensibility consumer api, so one can easily copy out parts of the neos-ui in a custom plugin for heavy modding (like i did lately with the PublishDropdown)

@mhsdesign Are you working on this task? otherwise i can take a look at it.
And just for sure, later on this should target the 8.3 branch, right?
