[katana] pass facts registry address to katana init

[glihm]

When working with katana init for provable mode, most of the time in testing the facts registry contract is mocked to always return a valid proof (and avoid long times of proof generation).

This issue aims at requesting a new feature in katana init where we could accept a facts_registry_contract_address for Katana to directly set it during deployment phase.

Or we may pre-register some mock facts registry on known networks.

Hi, I am a Cairo developer from Paris.
I already used Dojo engine contributing to Bytebeast project.
So I would be honored to be involved in the development of the engine!
I don't promise to finish the issue quickly because your codebase is new to me =)
But I intend to do a decent job and at least do the draft PR within 24 hours.
Could I try solving this?
