Support "multi-choice" input type for manual workflows

[DpoBoceka]

Describe the enhancement
Current set of input types doesn't cover some use-cases for manual workflows

We use a single gh-action as an entrypoint of deploying packages from our monorepo, and sometimes we need to manually deploy several packages simultaneously. Up until now we just went with a set of Booleans, so we could tick all the packages we needed to run our CI/CD against via UI. However, we speedily reached a limit of 10 input values

Introducing an input type that would store a, say, json array could help:

on:
  workflow_dispatch:
    inputs:
      name:
        type: multi-choice
        description: select packages
        options: 
        - go-service1
        - go-service2
        - py-service1

...and in fact would be more logical with less copy-paste overhead for our use-case

I run into the same problem. We want to select multiple schemes to build for our iOS App but we have way more than 10 schemes. It would be definitely a helpful feature. Otherwise, you have to work with the string input type, which can lead to input errors.

I would be really great feature to have since many use cases are there.
