Update Slider component implementation

[tayyabataimur]

• Separate Range Slider and Single Slider components to incorporate improved readability, best practices and accessibility.
• Use semantic elements (<input type='range' />) to get correct default behaviour.
• Simplify logic, ensure correct types usage.
• Update stories and tests

(Follow-up ticket to #4076)

Discussion points

• Should Range Slider and Single Slider be exposed as two different components in Salt similar to DatePicker or should we render one or the other based on prop values?
