[bmispelon]

Link to Ticket

Description of Changes Made

Added two new global navigation settings: footer_newsletter_cta_url and footer_newsletter_cta_text which are used in the footer component instead of the placeholder link and text.

How to Test

1. Go to Navigation settings
2. Populate the footer newsletter CTA link & text fields (all the way at the bottom) and save
3. Go to any live page and scroll to the bottom
4. The footer newsletter CTA should use the link & text from step 2
