Improvements of the hooks documentation

[c8y3]

These remarks all concern the documentation page on hooks (https://docs.dfir-iris.org/development/hooks/):

• Method register_hooks is mentioned in this page, but it is only explained later in the Processor modules page (https://docs.dfir-iris.org/development/modules/quick_start/processor/). I suggest to move the documentation page on hooks down in the Modules section and after the Quick Start
• rather than one table with all hooks, it would maybe be more readable to have three lists of hooks: postload, manual and preload
• could you please add a column in the hooks table to document the specific type of data that method hooks_handler will be called with for each hook? This is an import part of the contract between modules code and IRIS.

Thank you.
