Improve beta Github deployments

[pyby]

Motivation and Context

Following #447 and the first private and public betas (iOS and tvOS), the environment urls for private betas are wrong. Because of the bump build number commit during the workflow.

The deployment ref are links to the branch and could be links to the tag for more readiness.

Description

• Add tag support for GitHub deployment creation.
• Fix the environment urls for betas.
• Replace GitHub deployment for betas if new tag is created during the workflow with one with tag as a ref.

Checklist

• The code followed the code style as make quality passes with a green tick on the last commit.
• Remote configuration properties have been properly documented (if relevant).
• The documentation has been updated (if relevant).
• Issues are linked to the PR, if any.
