Add puppetcore support for Windows install tasks

Now possible to run the install task specifying puppetcore collection:

```
/opt/puppetlabs/bolt/bin/bolt task run puppet_agent::install \
  collection=puppetcore8 \
  version=8.11.0 \
  username=forge-key \
  password=${PUPPET_FORGE_TOKEN} \
  --targets 'winrm://HOST' \
  --user Administrator \
  --password ...
```

If the `windows_source` class parameter is explicitly given, then the task will
use that.

Also add additional logging as to where we are downloading the MSI from and the
exception message if downloading fails.
