graphminspantree function depreciated since R2022b

[juldub07]

graphminspantree used in minimalBridge line 235 throws an error because it has been replaced by minspantree

Suggestion:

    %     min_span_tree = graphminspantree(sparse(squareform(mindist)));
        min_span_tree = minspantree(graph(sparse(squareform(mindist))));

        % Map square indices to pair number
        ind2p = squareform(1:np);
        % Select the bridges that provide the minimal connectivity
        %     pair_bridge = pair_bridge(ind2p(min_span_tree > 0));
        pair_bridge = pair_bridge(ind2p(adjacency(min_span_tree) > 0));
    %         pair_bridge = pair_bridge(ind2p(find(min_span_tree)));
