Paragraph inside an inline block issue

When cloning a custom block with a paragraph inside the layout builder, an error occurs indicating that the paragraph cannot be duplicated with the same id and uuid. This occurs because when the block is cloned, the paragraph is copied with the same id and uuid.

Steps to reproduce

1. Create a custom block and add a paragraph to it.
2. Add the block to the layout builder.
3. Clone the block and observe the problem.

Proposed solution

Create a new ID and UUID for the paragraph
