Text style and icon in accordion item

[Francisco]

Description

Page: Home
Two visual improvements:

1. The answer displayed in the accordion item looks too similar to the question. That's because of the styles of both texts. My suggestion is to apply a bold style for question text.
2. The arrow aligns on the right should be 20px size (1.25rem).
3. The same icon does not rotate when opening the question to see the answer. It should rotate in 180º to indicate the box expanded.

note: the green outline is visible when the user focuses with their keyboard (tabbing trough the accordions) but not when they click the accordions with the mouse cursor.
