Child task: Create documentation about Kedro vs (or with) MLFlow

[stichbury]

Description

Child of https://github.com/kedro-org/kedro/issues/3012

## Context The context of this issue was to start to populate the Kedro docs with comparative content as it's an important part of a documentation set for users and for SEO. This is specifically for MLFlow.

This was a useful find while I was researching what to include.

I've decided to put this back in the backlog. I spent some time on it in Notion and thinking about how to rearrange existing docs to include a section for comparative/collaborative content about other products, but I'll be moving onto other areas so won't have time to take it forward at present.

@noklam already compiled some internal notes and I will try to get to draft the document structure this sprint.
