Vue3 compatibility for vue-apollo-smart-ops

**Is your feature request related to a problem? Please describe.**

Currently, [TypeScript Vue Apollo Smart Operations
](https://www.graphql-code-generator.com/plugins/typescript-vue-apollo-smart-ops) imports [vue-apollo-smart-ops](https://www.npmjs.com/package/vue-apollo-smart-ops) upon file generation

The issue is [vue-apollo-smart-ops](https://www.npmjs.com/package/vue-apollo-smart-ops)'s dependency is using [vue-apollo v3](https://www.npmjs.com/package/vue-apollo) (only supports Vue2) and will trigger an error below:


**Describe the solution you'd like**

Hence, I hope to see [vue-apollo-smart-ops](https://www.npmjs.com/package/vue-apollo-smart-ops)'s dependency updated to [vue-apollo v4](https://v4.apollo.vuejs.org/) with support for Vue3

**Describe alternatives you've considered**

For now, the workaround seems to be using [TypeScript Vue Urql](https://www.graphql-code-generator.com/plugins/typescript-vue-urql) which works well~!

**Additional context**

vue-apollo v4 package in [alpha](https://www.npmjs.com/package/@vue/apollo-option)
