Policy Hub with go native package resolving: how to test a policy before releasing

[malinthaprasan]

Problem:

With the previous policy hub implementation, we had each env specific storage buckets and we can progressively test and release to production policy hub.
With the native approach, if we add a tag with version, this will be the actual production release and will be instantly available to customers. We need a way to test, before releasing it.

Proposed Solution:

It looks like we can use pre-release tags (https://go.dev/ref/mod#glos-pre-release-version) before doing the actual tag with version, we should be able to add a pre-release tag corresponding to lower envs which will be used for testing etc.

eg: rate-limit/v1.0.0-dev1 (need to doublecheck the format)
