Fix POD warning in stylingprofile.pod

% pod2text src/doc/stylingprofile.pod.in > /dev/null
src/doc/stylingprofile.pod.in around line 207: Expected '=item *'
POD document had syntax errors at /usr/bin/pod2text line 84.
% podchecker src/doc/stylingprofile.pod.in
*** WARNING: =item type mismatch ('bullet' vs. 'number') at line 207 in file src/doc/stylingprofile.pod.in

I changed line 201 to be a numbered item instead, I think this
fits the structure of the document better,
