[Feature] Allow multi-guide contributions

[andyrodrigues30]

Problem

Currently users can only create one guide at a time.
If a user writes a long guide and wants to split it up into multiple guides, they will have to do it separately.
This breaks the flow of guide submission.
Users should be able to create multiple guides in one go - to improve UX and help with creating more atomic guides.

Proposal

Allow multiple guides to be created in one contribution step.
