[GNC] Links on wiki

[Peter C. S. Scholtens]

Hello,

On this page https://wiki.gnucash.org/wiki/Testing the weblinks in this 
text "Tests on C++ code should be written using GoogleTest and 
GoogleMock. " are dead. Please replace with 
https://github.com/google/googletest/blob/main/docs/index.md (I assume 
it can be one link).

Most likely, this is not the preferred way of communication, but I tried 
the following:
1. Request a wiki modification account -> After confirmation of the 
e-mail adress I got a "rejected request" message.
2. Went to Matrix bridged IRC channel #_gimpnet_#gnucash:gnome.org and 
posted the same message, but after 42 hours nobody read or reacted it 
(Several bridges report similar problems. As IRC has no memory and the 
channel is not used very requent why not switch to a Matrix only 
channel?).

This makes the threshold of contributing to open source quite high :-(
