error when wget is not available.

This is a good start for deno version manager.

I am on macOS, I've not installed wget and not plan to install wget too.

bash: line 48: wget: command not found

Please do not assume and use wget. There is curl, and the readme use curl -fsSL https://raw.githubusercontent.com/axetroy/dvm/master/install.sh already.

Now it no longer use the wget command. Thx
