Suppress webpack's critical dependency warnings for libheif

Supressing it for now since it obscures other important information in the console.

Upstream issue, which currently doesn't have a workaround:
https://github.com/catdad-experiments/libheif-js/issues/23

Full error message:

     ⚠ ../../node_modules/libheif-js/libheif-wasm/libheif-bundle.js
