Allow core post content block within wp-curate/query block

[kaitlinbolling]

Description

The core/post-content block is currently only allowed inside of the core/query block (see https://wordpress.org/documentation/article/post-content-block/). It would be great if this block was also allowed to be inserted inside the wp-curate/query block (within a post template), similar to other post- blocks.

Use Case

As an editor, I want to curate a list of events on a landing page. The event details and call to action is all within the event's post content, so I need to be able to add this to the post template within the query block.

Acceptance Criteria

• Ensure the Post Content block is available in the inserter inside of the Post Template block in a WP Curate Query block.
