fix: upgrade vite to solve vulnerability

[wilsonrivera]

Motivation and Context

I have upgraded the vite package by removing and reinstalling it in playground in order to solve a vulnerability caused by version <= 5.4.11

This was achieved with the following commands:

cd playground
pnpm remove vite
pnpm add --save-dev vite@^5.4.14
