TASK:

Description, Motivation and Context

This PR adds support for rightIcon and onClickRightIcon props to the multiselection mode of the MoleculeAutosuggest component.

Changes:

• Added rightIcon prop to display a custom icon on the right side of the multiselection input
• Added onClickRightIcon callback prop to handle click events on the right icon
• Implemented handleRightClick handler that passes event and current value to the callback
• Added demo example showing the rightIcon with interactive onClick handler
• Updated README documentation with usage examples for the new props
• Added tests to verify rightIcon rendering and onClick behavior in multiselection mode

Motivation:
This enhancement provides more flexibility for multiselection inputs, allowing developers to add custom actions via a right icon (e.g.,
search, submit, info tooltips) similar to what's already available in single selection mode.
