[Feature]: [@adminjs/relations] Add custom properties/columns.

[ZeroCho]

Description

I think one of good features for adminjs is to customize columns with custom components.
If @adminjs/relations also has a feature to customize columns, it will be better.

Suggested Solution

Like how we add custom properties for adminjs, I think @adminjs/relations should support properties column.
Please correct me if it already exists. As far as I know from searching from @adminjs/relations/types/index.d.ts, properties option does not exist.

properties: {
  params: {
    type: 'mixed',
    isRequired: false,
    components: {
      show: Components.ShowJSONB,
      edit: Components.EditJSONB,
      list: Components.ShowJSONB,
    },
  },
}
