Aruba platform integration doesn't work after upgrade ssh-rsa algorithm is deprecated

The problem

Apparently since I updated my Aruba 305 IAP access points they have closed the ability to use ssh-rsa as HostKeyAlgorithms which makes it impossible for me to track devices as HA can't connect any more and returns an unexpected response.

When trying to connect via Terminal/SSH manually ("ssh {user}@192.168.0.xxx, -o HostKeyAlgotiythms=ssh-rsa") the response is "Unable to negotiate with 192.168.0.xxx port 22: no matching host key type found. Their offer: rsa-sha2-512,rsa-sha2-256,ecdsa-sha2-nistp256,ssh-ed25519"

When I simply change the HostKEyAlgorithm in the query to rsa-sha2-512 it returns the fingerprint, asks for password and I can manually request the client list.

Firmware of Aruba IAP is "8.12.0.1_89864 SSR (Digitally Signed - Production Build)"

Diagnostics information

Line 92 in the device_tracker.py is not working for me any more due to the update by Aruba. The HostKeyAlgorithms=ssha-rsa is not supported any more and this code should be changed to HostKeyAlgorithms=rsa-sha2-512

Just contacted an Aruba expert and apparently ssh-rsa has been deprecated as it is deemed insecure (he couldn't tell me when exactly, though).

Therefore, the issue could only be fixed on the Aruba side by downgrading the Aruba IAPs which should not be a solution.
