Make ivy publication configuration optional

[bzzzzzz]

The plugin consumer might want to configure the publication in their way. In this case, the standard configuration we provide in the PegasusPlugin will harm them. We need to provide a way to disable this configuration, and this PR implements it.

Testing done

• Local build is ok
• Locally verified the new workflow works as expected
