Subject: [PATCH] always initialize member variable

in this change, impl::extended_p_square_quantile_impl::probability is
zero-initialized to silence -Wuninitialized warning from GCC-13.

despite that this variable is always initialized in
impl::extended_p_square_quantile_impl::result(), it is still referenced
by, for instance the copy constructor, which could be called before
`result()` gets called. and GCC-13 rightly warn us like:

In copy constructor ‘constexpr boost::accumulators::impl::extended_p_square_quantile_impl<double, boost::accumulators::unweighted, boost::accumulators::quadratic>::extended_p_square_quantile_impl(const boost::accumulators::impl::extended_p_square_quantile_impl<double, boost::accumulators::unweighted, boost::accumulators::quadratic>&)’,
