Handle "onlyLocals" breaking change

[slorber]

Hi, Docusaurus maintainer here.

On our next release, we upgrade a few dependencies to prepare the migration to Webpack 5.

There's a breaking change in the css-loader dependency that affects this plugin.
https://github.com/webpack-contrib/css-loader/blob/master/CHANGELOG.md#400-2020-07-25

Without this upgrade, you'll get an error such as

ValidationError: Invalid options object. CSS Loader has been initialized using an options object that does not match the API schema.
 - options has an unknown property 'onlyLocals'. These properties are valid:
   object { url?, import?, modules?, sourceMap?, importLoaders?, esModule? }

Note this is a breaking change for this plugin, as the new version published may not be compatible anymore with older Docusaurus versions, so you'd rather bump the major version.

As a sidenote, I'm thinking about creating a docusaurus community org with various plugins, would you be interested to move this plugin here so that it's easier for other trusted Docusaurus community members to do the upgrades?

[slorber]

@rlamana can you please merge/release this?

We are releasing Docusaurus and it's going to affect all users of your SaaS plugin that are going to upgrade.

---

For users looking for a workaround: use this dependency instead:

    "docusaurus-plugin-sass": "git+https://github.com/slorber/docusaurus-plugin-sass.git#patch-2",

You can also use patch-package or the Yarn 2 patch protocol to get this solved (get inspiration from jestjs/jest@6ae0b75)

@slorber I will merge and release these changes today.

[slorber]

thanks. :)

my proposal to move this package to a new docusaurus-community repo is still valid. Are you ok to add it?

Otherwise, we might still do it anyway because many users rely on this plugin and it can be annoying for them to wait for a publish :)

[rlamana]

docusaurus-plugin-sass v0.1.12 has been released.

@slorber I'll be more than happy to add it to the docusaurus-community repo, does it already exist? how should I proceed?

[slorber]

Thanks, it's not yet created but will ping you when it is ;)
