Task-util-config: add a select and multiselect instructions to util/config/configurator/configurator.ts

- Kind of request: feature request

# Problem

To create a wizard configurator, a selection of a choice or a multiple selection are needed.

Currently it's not possible to formulate questions such as:

- On which cloud provider(s) do you want to install Open Serverless (_more choices are possible_)?
- AWS
- Azure
- GCP

# Impact
100% of users that will install the ops

# Priority
high

# Expected outcome

1. The `multiselect` component of https://www.npmjs.com/package/@clack/prompts can be used.

# Suggested solution
None
