Enable 'Enter' key to move to the next line when Map block is selected

### Description:

Pressing Enter while focused on a map block should create a new paragraph block below, similar to the behavior of image and other media blocks. This ensures consistency and improves the user experience when working with map blocks.

### Steps to Reproduce:
1. Add a map block to the editor.
2. Place the cursor in the map block and press Enter.
3. Observe that pressing Enter does not move to the next line or create a new paragraph block.

### Expected:
• Pressing Enter while focused on a map block should insert a new paragraph block below the map.

### Actual:
• Pressing Enter does not create a new paragraph block or move to the next line.

No file, test, or entry point is named in the issue. Locate the map block editor implementation and compare its Enter-key behavior with image and other media blocks; done means pressing Enter with the map block focused creates a paragraph block below, verified through the editor reproduction steps.
