Description

In the current state, Docusaurus' autogenerated entries generates tiles looking like this:

Auto-generating entries is a great feature, and in my case, I'd like to use it to get scalable docs, such as listing many partners that my company integrates with.

For this, I would suggest to add the ability to customize the image that we add to the tile. Currently it's either the file or folder icon.

For example, adding this to the sidebar to specify a new image:

  {
          type: 'category',
          label: 'Essentials',
          link: {
            type: 'generated-index',
            title: 'Essentials',
            image: 'somelogopath.png'  <------- new
            description: 'my description',
            slug: 'dev/tutorials/essentials',
          },
          items: [
            'some link',
}

Or when generating tiles from a doc page with:

<DocCardList items={useCurrentSidebarCategory().items}/>

We could perhaps define the image in each entry in the sidebar.js file as well, using longhand notation:

   {
              type: 'category',
              label: 'My page',
              link: {
                type: 'doc', 
                id: 'dev/...', <------- contains the DocCardList component
              },
              items: [
               {
                  type: 'doc',
                  id: 'myDoc',
                  image: 'somelogopath.png'  <------- new
                },
              ],
            }

Motivation

I need this feature for scalability reasons so this feature will happen either on my own repo, but it should ideally be a core feature as it might help other users. I can possibly get a developer to submit a PR to your repo if you can share some pointers on how to do this 'the right way'.
