Draft: Fix overloaded functions have similar conversions
The Qt6 CI gets switched to MSVC 2022 now and with this the build fails with errors like this:
C:\builds\sysadmin\syndication\src\rdf\modelmaker.cpp(55): error C2666: 'Syndication::RDF::Resource::operator ==': overloaded functions have similar conversions
C:/builds/sysadmin/syndication/src/rdf/resource.h(79): note: could be 'bool Syndication::RDF::Resource::operator ==(const Syndication::RDF::Node &) const'
C:/builds/sysadmin/syndication/src/rdf/resource.h(79): note: or 'bool Syndication::RDF::Resource::operator ==(const Syndication::RDF::Node &) const' [synthesized expression 'y == x']
C:\builds\sysadmin\syndication\src\rdf\modelmaker.cpp(55): note: while trying to match the argument list '(T, T)'
with
[
T=Syndication::RDF::Resource
]
