Earlier this evening I tried to run the Go [modernize](https://pkg.go.dev/golang.org/x/tools/gopls/internal/analysis/modernize) analyzer on OPA. That didn't go as planned: - https://github.com/golang/go/issues/73661 - https://github.com/golang/go/issues/73663 While we wait for that to be fixed, I figured an old-fashioned search-and-replace across the repo may work for at least the `interface{}` to `any` conversion. That should help make it easier to see the other fixes as applied by the modernize tool once it has had those issues resolved. Signed-off-by: Anders Eknert <anders@styra.com>
