fix(FieldLabel): set the label of the labelTooltip info icon

[GuillaumeMMM]

User impact

Users of assistive technologies such as screen readers cannot get the information of the FieldLabel's labelTooltip. This PR adds the labelTooltip to the accessible name of the field's label.

Problem and solution fit

<Tooltip content={labelTooltip} placement="above">
          <Icon icon="info" size="sm" color="inherit" />
</Tooltip>

In this code from FieldLabel.tsx, the info icon component is called without a label prop. Therefore the icon's span container and its svg bear the attribute aria-hidden="true".
The Tooltip components links the content prop to its child with the aria-describedby attribute.

Since the icon has no accessible name, the aria-describedby is never appended to the accessible name, and thus never read.

The solution I suggest in this PR is to simply add the labelTooltip as the label of the icon, thus automatically removing the aria-hidden="true" of the icon's container, and adding to it an aria-label with the value of the tooltip's content.

On a side note, with this solution the aria-describedby still has no effect because the svg is still missing an accessible name. Another solution could be to add the reference of the tooltip's content to the aria-describedby attribute of the input itself.

Evidence

• Reproduction before the change:
  Turn on screen reader, focus an input that has an icon tooltip, the tooltip's content is not announced
• Result after the change:
  The tooltip's content is announced right after the input's label
