Make the WOTD feed discoverable

Problem/Motivation

While ✨ Support displaying the RSS feed icon on the WOTD block Fixed makes the feed discoverable if the WOTD block is present on the site AND the feed icon config is enabled, it does not make the feed discoverable if the feed icon is disabled or if the block is not present on a G2 page.

Steps to reproduce

Navigate to any page on the site, even those belonging to G2: observe that there is no feed icon and no meta alternate.

Proposed resolution

Add a meta alternate to the feed on relevant pages, like:

<link rel="alternate" type="application/rss+xml" 
  title="RSS Feed for the word of the day in the G2 Glossary on My Awesome site" 
  href="/rss/" />

Remaining tasks

• Decide on which pages to add it:
  • all pages ? maybe excessive, although doesn't hurt
  • G2 pages ? (main, homonyms, initials...): there's just a few of them
  • G2 entry pages ?
  • G2 admin pages ? is it useful there ?
  • Pages carrying the WOTD block ? Makes the most sense, but less visible than the whole site
• Do it
