This reduces the image size from 4.36 GB to 2.78 GB.

With this suggestion:

Warning: For production Image Optimization with Next.js, the optional 'sharp' package is strongly recommended. Run 'yarn add sharp', and Next.js will use it automatically for Image Optimization.

I added the sharp package.

There was a browserslist warning:

#19 48.93 Browserslist: caniuse-lite is outdated. Please run:
#19 48.93   npx browserslist@latest --update-db
#19 48.93   Why you should do it regularly: https://github.com/browserslist/browserslist#browsers-data-updating

So, I ran npx update-browserslist-db@latest, as the mentioned command is outdated.
