Get MINGW64 action running

[bridgetbarnes]

The gets need to be before golangci-lint is fetched, so move them earlier to prevent the action from failing because of missing dependancies

@bridgetbarnes thanks for having a look at this! Unfortunately, using get is not what we want here. get might/will modify the go.mod, which describes the dependencies of cobra. However, richgo and gox are not dependencies of cobra, but of the testing plumbing. See "No automatic changes to go.mod and go.sum" and "Installing an executable at a specific version" in https://blog.golang.org/go116-module-changes. See also #1366.

Oh awesome! Thanks so much for explaining, and for fixing it in your PR! Closing this now
