Find an opening paragraph tag and a minimum number of space characters
(i.e. not greedy).

Match any shortcodes and save them to the first backreference.
Match space characters to a closing paragraph tag.
"s" is a modifier for dot-matches-all mode, meaning that preg_replace
should treat everything like it's one big line.
So replace everything that matches all that with the backreference
that just matches the get_shortcode_regex() pattern.
