Add --dry-run feature to arkade get

[yankeexe]

Before downloading tools via arkade get it would be great to view what version of tool the user would be downloading upon running arkade get <tool-name> .

Expected Behaviour

The user being able to run --dry-run flag with a tool name to view what version of the tool is being downloaded, where the binary will be stored. In general what the download would look like without actually downloading the tool.

Current Behaviour

User comes and runs arkade get <tool-name> without being sure of what version is being downloaded, where it will be stored, and what to do upon completion of the download.
