Change Description

I think the comma was misplaced? I hope I'm not missing anything

[thomas-bc]

Some CI failures popping up that seem to suggest these checks weren't actually running with the wrong comma. Thanks! Want to fix the other failure or shall we?

[Saransh-cpp]

Thanks for the quick review! I can try fixing those and ask for help here if I struggle :)

[thomas-bc]

To fix formatting you can use an IDE supporting clang-format or on your branch in fprime: git diff --name-only --relative | fprime-util format --stdin

Thanks, @thomas-bc!

Thanks a lot for going through these! I'm confused about one of these warnings, but not a blocker in my opinion.
