LinkField support for has_many

LinkField support for has_many

Current React UI only supports has_one relationship for Link via the LinkField. We need to enhance this field to handle has_many relationship as well to enhance the CMS user experience.

Setup

Added a simple has_many relationship.

CtaBlock.php:

private static array $has_many = [
    'Links' => Link::class,
];

LinkRelationExtension.php:

private static array $has_one = [
    'CtaBlock' => CtaBlock::class,
];

Current state

We have to rely on GridField to manage these links as LinkField doesn't support this relationship setup. This functionally works but is far from ideal.

Desired state

The goal is the use LinkField with the Links relation in a similar way we can use UploadField to handle a has_many relation. We expect a React UI to be available to allow content author to manage multiple links via this field.

Impacted versions

This feature can be implemented only in GraphQL 4 compatible version as this is an enhancements. Back-porting this to the GraphQL 3 compatible is a nice to have but not manadatory.
