Update neopixel.js to fix detection of RPi CM4 with Bookworm

[Flos]

Types of changes

• [ x] Bugfix (non-breaking change which fixes an issue)
• [ ] New feature (non-breaking change which adds functionality)

Proposed changes

My CM4 Module has in /proc/cpuinfo no " : BCM" text string Wich leads to a false, failing Hardware check, and the NeoPixel nodes are ignored.

Instead of the "BCM" chip, /proc/cpuinfo shows "Hardware : Raspberry Pi Compute Module 4 Rev 1.1".

The Check was updated to use ": BCM" or ": Raspberry Pi" to check for Raspberry Pi Hardware.
