Breaking Changes

• Update eslint-config-prettier to v9 by @​WikiRik in https://github.com/vuejs/eslint-config-prettier/pull/18, which contains the following potential breaking change:

  Changed: unicode-bom is no longer turned off. Prettier preserves the BOM if you have one, and does not add one if missing. It was wrong of eslint-config-prettier to disable that rule. If you get ESLint errors after upgrading, either add "unicode-bom": "off" to your config to disable it again, or run ESLint with --fix to fix all files according to the rule (add or remove BOM). Thanks to Nicolas Stepien (@​nstepien)!
