librem5 bluetooth fix

We have a possible solution, all you need to do is to run these commands
(one by one) in a terminal on the Librem 5 or via SSH:

first command:

wget
https://source.puri.sm/angus.ainslie/firmware-rs9116-nonfree/-/raw/debian/master/Firmware/RS9116_NLINK_WLAN_BT_IMAGE.rps

second command:

sudo mv RS9116_NLINK_WLAN_BT_IMAGE.rps /lib/firmware

reboot the phone.

Let us know if that helped. If yes, you can later safely delete this
firmware with this command:

sudo rm /lib/firmware/RS9116_NLINK_WLAN_BT_IMAGE.rps
