[FIX] theme_*: adapt s_carousel_intro without display: flex

*: bewise, loftspace, monglia, notes, vehicle

In the community PR, the `s_carousel_intro` snippet has been modified in
order to not be in `display: flex` anymore.

This commit adapts this snippet customizations to these changes. More
precisely, it adapts the vertical padding and the grid areas to the text
content, in order to avoid having an overflow.

It also fixes the "Monglia" customization by removing the background
color of the slides, in order to make the added shape visible.
