[TOOL-3564] Playground: Select multiple chains in insight playground (#6652)

<!-- start pr-codex -->

## PR-Codex overview
This PR introduces a `MultiSelect` component along with a `useShowMore` hook to enhance the selection of network chains in a UI. It improves the user experience by allowing more items to be displayed as the user scrolls and provides a more flexible selection interface.

### Detailed summary
- Added `useShowMore` hook to manage displaying more items on scroll.
- Introduced `MultiNetworkSelector` for selecting multiple network chains.
- Updated `BlueprintPlayground` to utilize `MultiNetworkSelector`.
- Modified `ParameterSection` to handle array values for chain selection.
- Created `MultiSelect` component for better multi-item selection.
- Enhanced UI with search functionality and option rendering in `MultiSelect`.
- Implemented badge display for selected items in `MultiSelect`.
