Subject: [PATCH] Remove unused commands from the custom hardware configuration
 documentation (#2343)

## Description

#2255 introduced a new, cross-platform method for monitoring hardware
and removed the custom shell commands that had been used previously.
This PR updates the documentation to reflect the removal of those
commands from hardwareConfig.json.

## Meta

Merge checklist:
- [x] Pull Request title is [short, imperative
summary](https://cbea.ms/git-commit/) of proposed changes
- [x] The description documents the _what_ and _why_, including events
that led to this PR
- [ ] If this PR changes behavior or adds a feature, user documentation
is updated
- [ ] If this PR touches photon-serde, all messages have been
regenerated and hashes have not changed unexpectedly
- [ ] If this PR touches configuration, this is backwards compatible
with all settings going back to the previous seasons's last release
(seasons end after champs ends)
- [ ] If this PR touches pipeline settings or anything related to data
exchange, the frontend typing is updated
- [ ] If this PR addresses a bug, a regression test for it is added

 ## Hardware Interaction Commands
 
-For Non-Raspberry-Pi hardware, users must provide valid hardware-specific commands for some parts of the UI interaction (including performance metrics, and executing system restarts).
+For non-Linux hardware, users must provide the hardware-specific command for executing system restarts.
 
-Leaving a command blank will disable the associated functionality.
