fix dreference entry for *[N]T

[darthLeviN]

*[N]T can be dereferenced. Example :

test "dereferencing *[N]T works" {
    var arr: [3]u8 = .{ 1, 2, 3 };
    const ptr: *[3]u8 = &arr; // const, since we never reassign ptr

    // Dereference to get a copy
    const copy: [3]u8 = ptr.*;
    try std.testing.expectEqual(@as(u8, 1), copy[0]);
    try std.testing.expectEqual(@as(u8, 2), copy[1]);
    try std.testing.expectEqual(@as(u8, 3), copy[2]);

    // Mutate through pointer
    ptr[1] = 42;
    ptr.*[0] = 0;
    try std.testing.expectEqual(@as(u8, 42), arr[1]);
    try std.testing.expectEqual(@as(u8, 0), arr[0]);
}
