Add an option to add/edit alt text for videobox cover image.
What current pain point are you facing?
When adding a videobox to a wix studio website, the editor automatically selects a cover image. This image is used in the event of the video not being able to load, or before loading (see lazy loading for mode details).
Currently, there is no way to change the alt text for the cover image. This creates issues in SEO performance, as an image appears to have no alt text.
Do you have a current workaround that you’re using?
There is no workaround to this issue currently.
Describe the feature you need and how it would work. (Bonus points for mockups 
)

How will this impact you?
This feature will allow users to set and edit the alt text for cover images of videos, which leads to improvements in accessibility for site visitors as well as improvements for SEO.
