The right ray topologies on $\omega_1 (S220 and S221) are not injectively path connected.

Based on #1685 (comment) from @felixpernegger.

I added a metaproperty for P38 (injectively path connected) that is being used here. And took the opportunity to add some other ones, also for P37 (path connected) even if it's not used here.
