Accordion Block: Pressing Enter in empty Paragraph should exit Accordion Panel

[krokodok]

Description

Usually, pressing Enter in an empty Paragraph block exits the containing Block. This is the case for example in Group Blocks and Buttons Blocks. In the new Accordion Block, there is no way to exit the Accordion Panel. Combined with the fact, that there currently is no visual way (#77299) to tell if you are inside the Accordion Panel, or outside of it after it.

Step-by-step reproduction instructions

1. Create a new Accordion Block.
2. Move your cursor into "Type / to choose a block".
3. Press Enter.
4. The cursor should leave the block. But you are still inside it.

Alternative way to confirm this behaviour:

1. Create a new Accordion Block.
2. Move your cursor into "Type / to choose a block".
3. Press Enter.
4. Enter some text and press Enter.
5. A new, empty Paragraph should be created.
6. Press Enter again.
7. The cursor does not leave the Accordion block.
