Error when running for the first time: no download URL specified for snapshot files in config

[qlereboursBS]

Describe the bug We ran hornet and had this error: no download URL specified for snapshot files in config

To Reproduce

• Install hornet using the apt package: sudo apt install hornet
• Create a config.json with this content: {"dashboard":{"bindAddress":"0.0.0.0:8081","auth":{"sessionTimeout":"72h","username":"***","passwordHash":"***","passwordSalt":"***"}}}
• Run with hornet command

The output of the command is above

Expected behavior According to the documentation they should be downloaded automatically from trusted source thanks to hornet, and we shouldn't have this error.

Environment information:

• OS Debian 10
• RAM: 4 GB
• Cores: 4 Cores
• Type: VPS
• HORNET version 1.0.3
