include collection names on audit-log table

[JustRelaxable]

Hi, the current implementation of the plugin assumes the changes only comes from the users collection. However Payload CMS supports auth enabled collections, and it is important to log their changes too.
This PR aims to change auditor table column name: 'user', type: 'relationship', relationTo: 'users' to name: 'user', type: 'json', required: false to be able to save both CollectionSlug as well as the ID. I also tried to create a custom component to render default RelationshipInput on admin panel UI but with plugins it may not be possible to use custom component.

The aim is to save both collection name and id of the user, account or whatever auth:true collection and render RelationshipInput UI on admin panel.

Users collection:

App Account collection:

Thank you sincerely for your effort to improve payload-auditor.

Considering that currently payload-auditor performs somewhat weakly in default collection management, your idea is very good and practical and can solve a problem.

But we need to examine more aspects because this PR will change the depth of the plugin architecture and may increase the plugin size.

I will look into this as soon as possible.

Thank you for your cooperation
