The comma (,) is a range separator. See

:help 10.3
:help [range]

> /^\s*$/ find all blank lines (only zero or more whitespace)

/\S/,/^\s*$/

specifies the range of lines from the first one containing a
non-whitespace character through the next line containing only
whitespace (possibly none).

:help :j

It joins all the lines in the range.

The :g tells Vim to do this for all such ranges.
