Problem description

Following a link in a recent UG question, it becomes apparent that there is a mismatch of version between documentations (which after Cantera/cantera#1546 becomes a lot more apparent than it was in the past).

The link in the referenced document is https://cantera.org/documentation/dev/doxygen/html/d3/dd6/classCantera_1_1UnityLewisTransport.html#details
which originates here: https://github.com/Cantera/cantera/blob/5f1014c1a0c3f710db0cc2448e47bacddbb4617d/doc/sphinx/yaml/phases.rst?plain=1#L137-L149

There appear to be quite a few other instances where reST files point to the wrong version.

Additional context

While this appears to be a website issue, the offending documentation is part of the main repository.
