This moves the default CSS transformer and minifier to @parcel/css. The @parcel/transformer-css-experimental plugin is now renamed to just @parcel/transformer-css, replacing the old version. @parcel/optimizer-cssnano remains, but it is no longer the default in @parcel/config-default.

This PR updates the docs accordingly: parcel-bundler/website#1012.

In addition, I've added some warnings that will hopefully help the upgrade process.

  • When a cssnano config file is found

  • When a top-level "modules": true option, or "postcss-modules" plugin with no configuration is seen in a PostCSS config file. This can be replaced with using the "cssModules": true option for @parcel/transformer-css.

  • When "autoprefixer" or "postcss-preset-env" is seen in a PostCSS config file. These are now redundant with Parcel's builtin transpilation features via @parcel/css. This is similar to what we do for Babel. Not sure if we should have a way to suppress this one, given it's not 100% the same... but maybe we'll see how many problems it creates for people.
