Add vendor documentation links for PCM and PH configuration (#3135)

* Add vendor documentation links for PCM and PH configuration

Adds seealso boxes linking to CTRE PCM documentation and REV Pneumatic Hub documentation for configuration, firmware updates, and detailed technical specifications.

Fixes #2272

* Fix CTRE PCM documentation link to use chapter 09 instead of 08

* Update PCM documentation links per review feedback

Changes:
- Removed claim about 'technical specifications' (not available in CTRE docs)
- Added both CAN Bus Setup and PCM Bring-Up links as suggested by reviewer
- Added brief descriptions for each link explaining what they cover
- More accurate representation of what the CTRE documentation provides

 ## Wiring Overview
 
 A single PCM will support most pneumatics applications, providing an output for the compressor, input for the pressure switch, and outputs for up to 8 solenoid channels (12V or 24V selectable). The module is connected to the roboRIO over the :term:`CAN` bus and powered via 12V from the PDP or PDH.
