Migrate `table-tag-vue` in `ee/app/assets/javascripts/approvals/components/rules/rules.vue`

Detected usage of table tag inside JS/Vue file. Please use the GlTableLite component from @gitlab/ui if you want to display data as a table. If the table tag was used solely for layout purposes, like showing a diff side-by-side, consider using a different HTML tag. See https://design.gitlab.com/components/table/#when-not-to-use for more information.
