Description

Include the following attributes that were missing when an embed block is upgraded due to finding a more suitable block:

• align
• caption
• allowResponsive

How has this been tested?

1. Add an embed block.
2. Set an URL (YouTube video example: https://youtu.be/UOcroR50808).
3. Click on Embed button.
4. Change alignment to Align left.
5. Add text to the caption field.
6. Click on Show more settings (if they're not already displayed).
7. Uncheck Resize for smaller devices option.
8. Edit the URL by clicking on the ✏️ button located in the block's toolbar.
9. Set a URL from a different provider (Spotify song example: https://open.spotify.com/track/6UB9mShVLbMm0W4e6vud4C?si=3b03fa64857f4919).
10. Click on Embed button.
11. Observe that alignment is preserved (the value should be Align left).
12. Observe that the caption is preserved (the value should be the text set previously).
13. Observe that Resize for smaller devices option is preserved (the option should be unchecked).
