Description:
Please add a parameter to actions/setup-go to enable a customized download location of the Go toolset.

Justification:
Microsoft is directing teams to build Go applications with the new Microsoft build of Go tools. Rewriting action yml to download and extract the Microsoft builds of Go will cost a lot of time across the organization. Centralizing this capability in the existing setup-go action will save time and money. Their base URLs are different from google's but the paths per-version are the same.
