Publish provider artifacts (using minor version to start off)

## Context

This is a subtask of https://github.com/Azure/bicep/issues/10662.

In order for the bicep compiler to consume a provider types package we first need to be able to publish this package to the public Bicep registry.

## Acceptance Criteria
- A manually triggered CI job can publish the `az` provider package as an OCI artifact to the Bicep public registry given a manually entered package version

The issue names no files, tests, or entry points. Start by locating the CI workflow and the `az` provider package, then determine how a manually entered version can publish it as an OCI artifact to the public Bicep registry. Done means the manually triggered job publishes the package successfully with the supplied version.
