biorxiv_date is the date provided in those |biorxiv= parameter values that are dated at time 00:00:00 UTC

This function does not work if it is fed month names for languages other than English.  Wikimedia #time: parser
inputs:
apparently doesn't understand non-English date month names. This function will always return false when the date
<y>, <m>, <d> – year, month, day parts of the date from the birxiv or medrxiv identifier
contains a non-English month name because good1 is false after the call to lang_object.formatDate().  To get
<select> 'b' for biorxiv, 'm' for medrxiv; defaults to 'b'
around that call this function with date parts and create a YYYY-MM-DD format date.
