[BUG]: (doctest) build issue with glibc 2.34

[DeckerSU]

Since the SIGSTKSZ is no longer a statically defined variable:

• https://github.com/doctest/doctest/issues/473

build the project with glibc 2.34 will fail with error like this:

[ 71%] Built target komodo-wallet_autogen

gmake[2]: *** [src/CMakeFiles/komodo-wallet_tests.dir/build.make:349: src/CMakeFiles/komodo-wallet_tests.dir/Unity/unity_0_cxx.cxx.o] Error 1

It can be temp. fixed with something like:

sed -i 's/altStackMem\[4 \* SIGSTKSZ\]/altStackMem\[4 \* 8192\]/g' ci_tools_atomic_dex/vcpkg-repo/installed/x64-linux/include/doctest/doctest.h

before build.

But better to update doctest in a project from v2.3.8 to v2.4.8.

Thanks @DeckerSU If you can confirm v2.4.8 has passed sec review, we can update https://github.com/KomodoPlatform/doctest/ and I'll update the portfile.cmake in this repo to use the newer version in our fork
