The mechanism that both pack updating and Modrinth overrides use utilize std::filesystem::copy, which with GCC's libstdc++ has a bug on Windows where `overwrite_existing` isn't obeyed. In addition, made it clear what `overrideFolder` does by renaming it and rewriting an error message.
This prevents custom names from being lost when updating, by only
changing the name if the old instance name constains the old version,
so that we can update it if the user whishes to.

While working on pack updating, instance naming always gets in the way,
since we need both way of respecting the user's name choice, and a
standarized way of getting the original pack name / version.
This tries to circunvent such problems by abstracting away the naming
schema into it's own struct, holding both the original name / version,
and the user-defined name, so that everyone can be happy and world peace
can be achieved! (at least that's what i'd hope :c).
