impr(quotes): add English quotes (@JuniorKlumpy) (monkeytypegame#7180)

### Description

Added two new quotes as follows:

>Everything should be made as simple as possible, but not simpler.
– Albert Einstein

>Do you see him? Do you see the story? Do you see anything? It seems I
am trying to tell you a dream-making a vain attempt, because no relation
of a dream can convey the dream-sensation, that commingling of
absurdity, surprise, and bewilderment in a tremor of struggling revolt,
that notion of being captured by the incredible which is the very
essence of dreams.
– Heart of Darkness
