Updating existing font styles for accessibility

[eoke09]

For Accessibility reasons, we needed to update some of our smaller font sizes which resulted in the following changes:

Headline-5 9px —> 10px

Blocks/Components affected:

• Ad header “Scroll for more content”
• Category labels on feeds “read” “watch”, “look”, fotoscapes categories and image count

Overline and Body-2 got deprecated and those font instances are now using Subtitle as font style.

Blocks/Components affected:

• Subheader block “Recommended by …”
• Events
• Deals
• Video “Go to video” external link indicator in the header
• Horoscopes: a) date range in the horoscope bar b) date range in the horoscope teaser card c) “Today” text on horoscope detailed card
• Fotoscapes (text over image) subtitle

PriceTag-big and Month are essentially using the same exact styling, so just need to delete one (doesn't matter which)
