Stylelint 16 requires exposed ruleName

[elycheea]

Was reviewing a dependency update which updates to Stylelint 16 and caught this during a CI check.

Downgrading Stylelint back to 15.11.0 and Prettier down to 2.8.8 gets our lint passing again.

Running audit using: yarn npm audit --environment production --severity moderate
Error: stylelint requires plugins to expose a ruleName. The plugin "/Code/ibm-products/node_modules/stylelint-plugin-carbon-tokens/dist/index.js" is not doing this, so will not work with stylelint. Please file an issue with the plugin.

Previously documented in this PR https://github.com/carbon-design-system/ibm-products/pull/4168#pullrequestreview-1863853796.

This is a bit trickier than first glance @elycheea

The rules do have rule names but in moving from 15 to 16 stylelint does not interpret the CJS plugin as having them seeing 'default' when looking for rulename

As opposed to an ESM module at the same break point

Converting to ESM on the face of it seems simple enough but hits a number of issues.

• Node and as a result Jest only have experimental support for ESM. So it might be necessary to switch to stylelint-test-rule-node https://stylelint.io/developer-guide/plugins#testing
• Importing JSON files is also experimental and needs to be reworked.

@elycheea you are now blocked by a carbon dependency on stylelint-a11y perhaps switch to @double-great/stylelint-a11y
