Support multiple versions in a single invocation

I know I can do this:

- name: Setup dotnet
  uses: actions/setup-dotnet@v1
  with:
    dotnet-version: '2.1.811'
- name: Setup dotnet
  uses: actions/setup-dotnet@v1
  with:
    dotnet-version: '3.1.404'
- name: Setup dotnet
  uses: actions/setup-dotnet@v1
  with:
    dotnet-version: '5.0.100'

but I’d like to do this:

- name: Setup dotnet
  uses: actions/setup-dotnet@v1
  with:
    dotnet-versions: ['2.1.811', '3.1.404', '5.0.100']

@vsafonkin thanks for the update.

FWIW, this is the first time (to my knowledge) that a maintainer has commented on this issue. Given the enthusiasm shown for it (currently 36 upvotes) it would be nice to have received some response a little earlier, even if it is just “not now, but later”. It’s good to know that you have this in your sights. 👍
