Change Vue 3 presets configs

• Change plugin:vue/vue3-essential config:
  • Add vue/no-child-content rule
  • Add vue/no-expose-after-await rule
  • Add vue/no-reserved-component-names rule
  • Add vue/no-use-computed-property-like-method rule
  • Add vue/no-v-text-v-html-on-component rule
  • Add vue/prefer-import-from-vue rule
  • Add vue/valid-attribute-name rule
• Change plugin:vue/vue3-strongly-recommended config:
  • Same changes as above
• Change plugin:vue/vue3-recommended config:
  • Same changes as above

Change Vue 2 preset configs

• Change plugin:vue/essential config:
  • Add vue/no-child-content rule
  • Add vue/no-reserved-component-names rule
  • Add vue/no-use-computed-property-like-method rule
  • Add vue/no-v-text-v-html-on-component rule
  • Add vue/valid-attribute-name rule
  • Add vue/valid-model-definition rule
  • Add vue/no-export-in-script-setup rule *

Note: The rules marked with * are now included in the plugin:vue/essential config because @vue/composition-api and unplugin-vue2-script-setup add (limited) support for these Vue 3 features in Vue 2. If you don't use those libraries, enabling these rules shouldn't affect you.

• vue/no-invalid-model-keys rule is now deprecated, as it's renamed to vue/valid-model-definition
• vue/script-setup-uses-vars rule is now deprecated, as it's no longer needed with the upgrade to vue-eslint-parser to v9
• vue/setup-compiler-macros environment is now deprecated, as it's no longer needed with the upgrade to vue-eslint-parser to v9
