Remove unneeded strings from EDU coexistence setup flow

Two list items from 'G Suite for Education accounts' are removed:
* Info about child data
* Resources for schoolwork

This cl needs to be merged back to M84, so it will be followed by
a cleanup cl that removes string resources.

The new screen look: https://photos.app.goo.gl/FzJqSEu8YXvXg7Pg9
