Bump webpack from 4.46.0 to 5.18.0 in /www

[dependabot-preview]

Bumps webpack from 4.46.0 to 5.18.0.

Release notes

Sourced from webpack's releases.

v5.18.0

Internals

• refactor hashing to move the responsibility of hashing module exports info and referenced modules from Dependencies to the Module
  • Hashing in Dependencies can be much cheaper now (could improve performance when many dependencies are used that point to the same module, like many references to React.createElement)
  • Fixes bugs where Dependencies forgot to hash some details about the referenced module
  • The new model elimiates the potential of such bugs are Dependencies have less responsibilities now

v5.17.0

Features

• add experimental lazy compilation via experiments.lazyCompilation: true for web and node targets
  • compiles entrypoints and import()s only when they are accessed
  • More details see: webpack/webpack#12469
  • Known issues: webpack-dev-server/webpack serve opening an entrypoint for the first time, sometimes need a manual refresh.
• move some javascript parsing related configuration options from module to module.parser.javascript and also allow to set them via module.rules
• add module.parser.javascript.commonjsMagicComments to enable /* webpackIgnore: true */ for require() calls

Bugfixes

• fix a problem with webpack.debug.ProfilingPlugin on Mac when the computer was suspended before.
• fix a bug with IIFE handling when the IIFE has parameters with default values

v5.16.0

Features

• add __webpack_is_included__("./some-module") which returns true when the module is bundled and false when not
• priorize eager shared modules over normal shared modules (with the same version), as they are loaded anyway
• add library.type: "assign-properties" which merges all exports into a global variable
• allow optimization.innerGraph for new URL()
  • This allows to detect which URLs are used and drop the module and asset when they are not.

Bugfixes

• only return exports from runtime when needed
  • This allows to use experiments.outputModule: true with optimization.runtimeChunk
• fix a bug that splitChunk.reuseExistingChunk doesn't work for entrypoints
  • This optimized an edge case where a nearly empty entrypoint is created when an entrypoint contains only vendor modules

Developer Experience

• include plugin names in deprecation message for "NormalModuleFactory.xxx is no longer a waterfall hook"
• improve error message when passing an invalid library name

v5.15.0

Features

• add getResolve method to data object when using function externals
• externals function may return a promise now
