field_overlay_sizing* seperate-box => separate box

For now we decided to keep the wrong values, although I don't like it, as it will cause hard to find bugs, if someone types the correct key.

Fixing this requires

• an update hook to update the values
• change in the template where the value is used

@thomas.frobieter should we use the chance to fix this now combined with ✨ Provide list_string field values and defaults programmatically Active ?

Then @lrwebks could do it.

I have to admit, I don't care about this typo. Not a bit. The Media slide template is often overridden in our custom themes, I need to scan them all for this.. extremly minor issue.

So we could leave it open, but I don't think I'm going to spend time on it any time soon.

Ok!
