PMSA0031 sensors require ~3secs before coming up on I2C (#4743)

Browse Source 
* PMSA0031 sensors require ~3secs before coming up on I2C

As reported by @MALAONE1 and debugged by @shodan8192 , PMSA0031s
on a RAK4631 take 3 seconds before they can become detectable on I2c.

Add a delay(4000) before I2C scan if the air quality sensor pin
is defined.

Fixes https://github.com/meshtastic/firmware/issues/3690

* Remove 4 second wait and rescan during air quality init for the sensor

* works without but this triggers my OCD
