Create documentation for content editors about zimit offliner

[benoit74]

Just like we have done recently for Youtube offliner, we need to create a documentation for Zimit offliner.

Current documentation about Zimit Ticket Lifecycle is mostly useless since it only reproduces generic documentation, so from my PoV this should be removed and centralized in a "Generic Recipe Lifecycle" (which could also be part of the "Overall content edition process").

We discussed a bit about it Friday and agreed that many content has already been produced in various explanation in various tickets, so I need help to gather this.

I also realized yesterday that documentation about scope, include, exclude is not that bad on Browsertrix Crawler README. Even if not really easy to follow, at least there are important information detailed.

Would you please help me to gather all existing documentation or explain/write what needs to be?
