Education notice: update background color

[randybascue]

Description

Problem

The --color-background-education variable is currently a hard-coded hex value. This value arose due to not having a core value available that matched the proposed design.

Solution

Update --color-background-education to match the latest design specs.

Light theme

--color-background-education: --color-core-blue-100

Dark theme

--color-background-education: --color-core-indigo-800

Acceptance criteria

The --color-background-education value is updated to the latest spec for dark and light theme.
