Add acceptance tests for nested array + documentation

[jannyHou]

Suggestion

Add shared acceptance tests of nested array property for all connectors

cc @agnes512 based on discussion in #5559 (comment).

Use Cases

With memory connector, people can define nested array property as:

  @property.array(Array,
    {
      jsonSchema: {
        type: 'array',
        items: {type: 'string'}
      }
    }
  )
  nestedArr: Array<Array<string>>;

We'd like to verify the CRUD behaviours of such property in different connectors.

Acceptance criteria

• Add shared acceptance tests for nested array property for all connectors, the tests should cover CRUD operations.

• If any connector doesn't support nested array, or any particular operations, document it.
