fix(kad): remove default IPFS protocol name

[guillaumemichel]

Description

Fixes: #5006.
Related: #5015.

Notes & open questions

Following suggestions from #5015 (comment)

• NOT removing the Default trait for kad::Config and kad::ProtocolConfig, but documenting it as deprecated.
• Adding new constructors kad::Config::new(Vec<StreamProtocol>) and kad::ProtocolConfig::new(Vec<StreamProtocol>) to be used instead of kad::Config::default() and kad::ProtocolConfig::default().
• Adding a manual deprecated kad::Config::default() and kad::ProtocolConfig::default(), to prevent users from calling default().
• Deprecating kad::Config::set_protocol_names and kad::ProtocolConfig::set_protocol_names, they should be replaced by kad::Config::new(Vec<StreamProtocol>) and kad::ProtocolConfig::new(Vec<StreamProtocol>).
• Updating code calling deprecated functions.

• This change is expected to be backward compatible.
