[BUG] Klipper SKR Mini 3 V3.0 supplied default printer.cfg file has error in the BL touch section

[misterkaplan]

BigTreeTech supplies an example printer.cfg file for the SKR Mini 3 v3.0 for Klipper here:
https://github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/blob/master/firmware/V3.0/Klipper/SKR-mini-E3-V3.0-klipper.cfg

But there is an error in it.

Here is the section copied and pasted from the file:
[bltouch]
sensor_pin: PC14
control_pin: PA1
x_offset: -40
y_offset: -10
z_offset: 3.0
#speed:

The error is in the sensor_pin: line. It's supposed to be:

sensor_pin: ^PC14

The ^ is missing in the original.
According to the official Klipper documentation, "Most BL-Touch devices require a pullup on the sensor pin (prefix the pin name with ^)."
https://github.com/Klipper3d/klipper/blob/master/docs/BLTouch.md

Once I added the ^, it worked correctly. Without the ^, I got lots of errors like "BLTouch failed to verify sensor state". I also noticed that the pin on the BL touch would not retract back up when it touched the bed (or even my finger).

Please fix the default file.
