Review docs for lists and ensure they are bullets/numbers according to the information they present

[stichbury]

This is issue #965 on the internal repo. It's perfect for an external contributor and they don't need any major awareness of Vizro.

Docs change is needed where bullets are used in docs and present a sequence of actions -- this should be a numbered list.
Likewise, if a numbered list is used, it should be because the items need to be done in that particular sequence.

The task is to review each page of the core and vizro-ai docs and check where bullets are used to confirm they're correctly formatted. There may be some lists that we don't need (and it may sometimes make sense to add them, but that's an extension task).
