Fix gcc11 (ubuntu 22.04) issue with catch2 and MINSIGSTKSZ
This error occurs with gcc 11.2
/src/ezcar2x/3rdparty/catch/single_include/catch2/catch.hpp:10822:58: error: call to non-‘constexpr’ function ‘long int sysconf(int)’ 10822 | static constexpr std::size_t sigStackSize = 32768 >= MINSIGSTKSZ ? 32768 : MINSIGSTKSZ;
The error war fixed in catch2 v2.13.5
