fix: vue/multi-word-component-names should be universal

The vue/multi-word-component-names rule is applied to both Vue 2 and
Vue 3 versions of the eslint-plugin-vue package for essential,
recommended, and strongly recommended rule sets. So, when we disable
this rule, it should be for both Vue 2 and Vue 3.
