Bluetooth state powered off
### What issue do you have? Please be as thorough and explicit as possible.
The Govee plugin is unable to scan for Bluetooth devices due to: [Govee] [noble] stateChange: poweredOff when Homebridge boots up. Anytime I try to control the lights, it reverts to API because Bluetooth is not in correct state.


### Details of your setup.
* Do you use (1) Homebridge UI-X (2) Homebridge CLI or (3) HOOBS? 
Homebridge UI-X


* Which version of Homebridge/HOOBS do you have?
1.3.8


* Which platform do you run Homebridge/HOOBS on (e.g. Raspberry Pi/Windows/HOOBS Box)? Please also mention your version of Node.js/NPM if known.
In a Docker container running on an Unraid host. The host detects my Bluetooth dongle as:
Bus 001 Device 018: | ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode) and Unraid loads the proper drivers.

Node.js v16.13 & Npm v8.1

* Which version of this plugin (homebridge-govee) do you have? Has the issue started since upgrading from a previous version?
v4.18


* Which Govee devices do you have that are causing issues? Please include product models if applicable.
H6159
