Validation Error When Using Only Relative Media Directories

[Undistraction]

Describe the bug
The beta docs here outline how collection-specific media_folder keys can allow you to use relative paths. This effectively removes the need for a global media_folder key. However it appears this is still being validated as a required key.

Error loading the CMS configuration
Config Errors:
config should have required property 'media_folder'
config should have required property 'media_library'
config should match some schema in anyOf
Check your config.yml file.

I think there might be some kind of conflict between local and global dirs causing the bug I have outlined in #3654 which is why I removed the global dir.

To Reproduce

Expected behavior
No validation error.

Hi @Undistraction, the global media_folder is required for collections that don't have media_folder specified and also since you can use templates to refer to refer to the global one, e.g. under a collection you can specify media_folder: {{media_folder}}/posts_images (this is not document yet though).

@erezrokah Thanks for the explanation. That's a nice feature (being able to organise images within a central media directory).

I know that relative media directories are only a beta feature but would be great to add something to the docs highlighting that a global for is still required in the config even of you aren't using it.

Good point @Undistraction, we've recently added the media folder templating and field based media folders. It is not even documented yet since we want to gradually gain confident with the current approach and get more use cases.
Closing this issue, as will open a new one to improve the docs.
