* Make it easier to find network modules
Feedback has been it's difficult (via Google or directly) to find
modules as some people search for the company name vs product name,
therefore specify both.
* "IOS XR" (not "IOS-XR")
In old IOSXR versions, 'show commit changes diff' does not work.
Fall-back to 'show configuration' if that command fails so execution
can move forward.
Fixes#22235
