[FEAT]: Improve preview in REPL

### Description First of all, thanks for your work! It's super useful :) One of the issues I encounter is with the REPL. It's always hard to find an icon and the matching name. Imo, it would be super useful if the icon name is displayed alongside the icon. I suggest you this solution: ```svelte <script> import * as Icons from 'svelte-heros-v2'; const random_hex_color_code = () => { let n = (Math.random() * 0xfffff * 1000000).toString(16); return '#' + n.slice(0, 6); }; </script> <div class="container"> {#each Object.entries(Icons) as [name, component]} <div class="icon"> <svelte:component this={component} color={random_hex_color_code()} /> {name} </div> {/each} </div> <style> .container { display: grid; grid-template-columns: 1fr 1fr 1fr; gap: 8px; } .icon { display: flex; gap: 4px; align-items: center; } </style> ``` ### Additional Information _No response_
