Description

• Removes a warning during build creation about chunk size. We can explore chunking later but it's not necessary for a our kind of application
• Remove webpack.extension.config.js, it is not used anymore
• Created a import for 'p5' global variable

Relevant Technical Choices

Unfortunately, is not possible to remove '<script src="./p5.min.js"> in "/index.html" can't be bundled without type="module" attribute' warning

Testing Instructions

1. Pull and checkout the branch improvement/vite-follow-up
2. Build and run the extension: npm run start or npm run build:all
3. Observer: There are not warning in the console(usually represented with yellow color)
