Add Subscription option to https://experience.workfront.com/s/new-workfront-experience

[#1]

During the development of materials and content supporting the New Experience, as new materials are uploaded to the website for customers, it would be valuable to have some sort of subscription or "follow" capability to indicate to customers that new content is available. In addition, some sort of "update" feed on the home page to link to the new content. Otherwise, customers need to peruse the whole site in order to find new content.
