Documentation page design improvement

[QubitPi]

The documentation page texts looks great. The front page style though can be improved.

• The theme color of red is OK but needs to be justified ("why would we choose this color") or otherwise should be changed
• The logo needs to be changed from the green "dynasore" to the one that fits Aristotle
• Aristotle currently is independent on deployment, so the "Immutable Infrastructure" doesn't apply. Need to change to something else

We can ask some UI or Design majors to do some of the works for us if possible
