Core plugin installation utility

### 🚀 Feature Proposal

A CLI utility within `fastify-cli`. The process could be similar to the one you go through when you run `npm init`.

### Motivation

If you create a new project using `fastify-cli`, you will normally also use plugins, e.g. for authentication or database access. However, I find it unnecessarily time-consuming to find out the names of the desired plugins, i.e. whether it is now called `fastify-postgres`, `@fastify/postgres` or `@fastify/pg`. Since a list of core plugins is also maintained in the docs, `fastify-cli` could contain a utility for the installation of core plugins. This could also be categorised according to subject areas, e.g. `authentication`, `database access`, `security`, etc.
