Output version to stdout rather than stderr

[radeksimko]

This seems like an unfortunate oversight:
https://github.com/hashicorp/vscode-terraform/blob/1c882b35bb52e834214fad186c167f8ecaf04804/src/languageServerInstaller.ts#L32

I'm not sure yet how to fix it in a backwards-compatible way though and what would happen if stderr became empty.

Server Version

0.3.2

Expected Behavior

terraform-ls --version printed out to stdout.

Actual Behavior

terraform-ls --version printed out to stderr.

I suspect the major "customer" of this API is really just VSCode for now and I'm thinking we could just read stdout+stderr for a while: hashicorp/vscode-terraform#418
