chore: use https for git submodules to use CA PKI instead of SSH TOFU

[nxxxse]

Description

For users just cloning this, ssh is incontinent because of

The authenticity of host 'github.com (140.82.121.4)' can't be established.                                                                                    
ED25519 key fingerprint is SHA256:+DiY3wvvV6TuJJhbpZisF/zLDA0zPMSvHdkr4UvCOqU.                                                                                
This key is not known by any other names.                                                                                                                     
Are you sure you want to continue connecting (yes/no/[fingerprint])? no        
Host key verification failed.                                                                                                                                 
fatal: Could not read from remote repository.

Defaulting to HTTPS avoids this.
