redis-info script does not talk TLS

[digininja]

Describe the bug
One for @patrikkarlsson or @segoon. The redis-info script doesn't talk TLS so it can't be used against a redis server which only supports TLS based connections.

To Reproduce

The server only allows connections over TLS:

└─$ redis-cli --scan --pattern '*' --tls  -h 10.1.0.1 
info...

When scanning with the script, no data is retrieved:

└─$ nmap --script redis-info 10.3.0.43  -Pn -p 6379 -n
Starting Nmap 7.93 ( https://nmap.org ) at 2024-05-23 09:30 UTC
Nmap scan report for 10.1.0.1
Host is up (0.00075s latency).

PORT     STATE SERVICE
6379/tcp open  redis

Nmap done: 1 IP address (1 host up) scanned in 30.24 seconds

Expected behavior
The script should try clear text first and then if it can't get anything, try a TLS connection.
