[MartaPintoTeixeira]

Current behavior

There is no space between "Help-text" and the input boxes - Margin-top is not active.
There is no space between "max attribute" or "min attribute" etc .. and the input boxes - Margin-top is not active. - code only

Expected behavior

We should apply the same margin-top that we have in between "Error message" and input box.
Which in FIGMA is: 4 in figma.
Which in CODE is: margin-top: var(--sd-spacing-2, .5rem);

Steps to reproduce

Open storybook and figma.
