Consider adding OG alt tag

We recently added alt text to the system, and we should consider adding the og:image:alt meta element to expose it for social sharing.

Yoast recommends against this. Their reasoning is that in the context of share cards, it’s actually more confusing. I don’t know enough to be sure, just flagging that we should look into how others have handled it before we add it ourselves.
