Add keys for BT/BLE profiles management in the keymap

[nam-ori]

For bluetooth (BLE) keyboards, the default keymap lacks BT management keys. I have opened an issue on the zmk-config-selenium repos for the ZMK firmware.

I don't know if other firmware builders (the ones with bluetooth connectivity) would have the same needed keys. We could see that when this case shows. In the meantime, I propose to reflect my proposal for the ZMK firmware in the pictures.
