Table row on hover should not be transparent #964
Description
Describe the bug
When hovering a table row, the background is a color with 12% opacity. When there's a sticky column (ie: the action column on the right), when hovering a row, the background is no longer opaque and therefore the content of the sticky column (in the front) overlaps the content below, making it hard to read.

To Reproduce
Find a table with a sticky column (ie: https://mia-platform.github.io/design-system/?path=/story/components-table--scroll) and hover on a row; try scrolling horizontally so see the content below the sticky column appear.
Expected behavior
When hovering a row, the content of the cell in the sticky column should be readable and shouldn't be possible to read the content below; therefore, it suggested that a white background is added to the container of the cell.
