add date format HUMAN_SINCE

add date format HUMAN_SINCE add date format HUMAN_SINCE_STRICT

Description

I'd like to be able to have lume display an article as having been written "three days ago" rather than "March 23, 2024", but the date package doesn't currently support relative dates. I've exposed functionality in the already-relied-upon date-fns package to add two new date formats:

• "HUMAN_SINCE", exposing formatDistanceToNow, and
• "HUMAN_SINCE_STRICT", exposing formatDistanceToNowStrict.

Note: I have done everything on the check list below, but that check list does not tell me how I would update the plugin's documentation.

I proposed a fix without opening an issue.
