Do not use stylelint-processor-styled-components, it is deprecated

Do we have any updates on this? Older versions of stylelint contain vulnerabilities, so rollback is not an option here 😕

In case it helps anyone. I resolved the same problem by installing "postcss": "^8.4.17", as a direct dependency.

EDIT: Apologies, I got it working without stylelint-processor-styled-components by just wiping my node_modules and yarn.lock file. Must have been a missing package.

Could I re-open this issue please?

Removing stylelint-processor-styled-components produces the following type of error for all plugins: Could not find "stylelint-config-standard". Do you need a configBasedir?: E.g. https://github.com/AtomLinter/linter-stylelint/issues/68

Using stylelint-processor-styled-components produces the above TypeError: TypeError: Cannot read property 'stringify' of null at Root.toString

@evilebottnawi do you have a recommendation on what to do to use stylelint with styled components properly? Or is currently impossible to use stylelint with styled components due to the postcss-jsx issue?
