feat(stylelint ✨): add support for stylelint 14

[manbearwiz]

BREAKING CHANGE: Requires stylelint@^14, config change

Stylelint removed the configOverrides option. The config passed to stylelint now replaces the configuration loaded from .stylelintrc.

See the Stylelint Migration Guide for details.

If you would prefer to handle this stylelint breaking change another way, please let me know. Stylelint does expose a resolveConfig function to get the config for a file; however, that would mean calling resolveConfig and lint on each file individually.

Thanks for the PR! The resolveConfig option sounds interesting, I guess that makes it more like how ESLint runs, where different files can have wildly different configs. It could line up with ./packages/eslint/src/eslint.ts quite nicely?

@phenomnomnominal - do you know the status of this pls? Whilst not the current version of stylelint (16.2.1), it seems like this would be a step in the right direction. I've not found any combination of packages that work with the betterer stylelint test and the stylelint configs stylelint-config-standard and stylelint-config-standard-scss which is preventing me from making use of betterer.

If we could work towards using the latest version of stylelint as a peer dependency, that would be ideal.

Looking through old stuff and I realized I never followed up. I looked into making it run on each file independently, but the performance was terrible.
