Based on idea: https://planet4.greenpeace.org/idea/add-time-length-to-post-details-e-g-2-min-read/

User Stories

• As a Greenpeace supporter, I want to see the reading time for articles so I know approximately how long it will take me to read them.
• As a Greenpeace author or editor, I want to show the (automatically generated) reading time to a post so that readers are encouraged to click through and read articles.

Requirements

• should be styled according to our design systems / fonts
• solution should have support for non-latin characters
• should investigate both manual and dynamic (generated automatically based on word count) options for setting reading time (automatic for MVP)
• solution should have ability to indicate which post types reading time shows up on
• if we decide to move forward with this feature, we should define success metrics and possibly a/b test to see if it does, in fact, increase time on page/scrolling distance, etc.  (Striking this through as a non-tech requirement, but jmarubay let us know if there is something needed from our end)
• Investigate videos length estimation for certain providers.
