This uses more arguments in the GET request for mod versions on the
Modrinth API, filtering what versions can be returned, decreasing load
on Modrinth servers and improving a little the time it takes for the versions to be
available to the user.
This also removes the now unneeded check on correct modloaders in
ModrinthPackIndex, since it is now filtered by the Modrinth server.
Lastly, this adds a couple of helper functions in ModModel.
The checks used are roughly the same as the ones proposed in the
clang-tidy PR (except perhaps that I used modernize-* instead of listing
them individually,though I don't think this caused any readability
detriments).
In ModrinthModel.cpp and FlameModModel.cpp I ignored the
modernize-avoid-c-arrays one, mostly because making the sorts array an
std::array would most likely increase the code complexity because of the
virtual function. Aside from that, the static_cast warning from
Application.h was not dealt with, since it's not in this PR's scope.
