Unreviewed build fix.

std::derived_from is a C++20 feature that's nearly the same as the C++11 feature std::is_base_of_v;
since it shouldn't make a difference for this particular case, let's just make use of the latter.

* Source/JavaScriptCore/runtime/SideDataRepository.h:
(JSC::SideDataRepository::ensure):
Use std::is_base_of_v<Base, Derived> instead of std::derived_from<Derived, Base>.
