Bias-tee option missing for rtl_tcl device

[jelleh]

Describe the bug
The bias-tee option is missing for the "RTL-SDR device (via rtl_tcp)" device settings

To Reproduce
Connect to rtl_tcp, look in to the rtl_tcp output, when connecting, it sets the default "set bias tee 0"
But it can not enabled in device settings and profile settings on the web ui.

Expected behavior
Should be available, it is a working setting like "set direct sampling 2" that one is working, and available in the settings.

Installation method
Docker

Versions
Latest docker image: slechev/openwebrxplus (deployed on 2024-8-3)

Log messages
You can see OpenWebRX connecting to rtl_tcp and setting the default "set bias tee 0"

Additional context
None

When setting "bias_tee": true, in var/settings.json for the rtl_tcp device, it works.. so it is realy only missing on the web ui
