[Events v3 - Fast-follow] [BUG] Event sharing via social media has content missing

[mmiddaugh]

Issue Description

When we share an event using a social link, there’s some JS code that tries to get some content out of the metadata. That content is missing on our event pages, so all that gets shared is the URL (the content is not included.) This occurs on VAMC and outreach events (past and current/future). e.g. https://www.va.gov/pittsburgh-health-care/events/walk-in-covid-19-vaccination-clinic/

It may have always been present and intended behavior is unknown by this team.

Today we get title + URL. Probably still want dates / times pushed.

@FranECross Check to see what all metadata we want to display (images/dates/times/what?)
