Automate Request Network SDK release process with Github Action

[MantisClone]

Problem

The release process involves manual steps.

Desire

The release process should execute automatically when tags are applied to the master branch.

Details

The current release process uses scripts located in https://github.com/RequestNetwork/release-tools. The docker release steps are semi-automated by github actions in https://github.com/RequestNetwork/docker-images that can be executed manually.

The release process is prone to error so automating might not be advisable right away.
