No Class in opentelemetry-runtime-attach jar

[jufab]

Description
I wanted to try opentelemetry-runtime-attach module.
I import it in maven project.
But when I would like to import RuntimeAttach : there is no class.
In jar, there is only otel-agent.jar in io.opentelemetry.contrib.attach

Steps to reproduce
Just open jar from maven and see the content

Expectation
Find RuntimeAttach.class in jar

Relevant Environment Information
Version: 1.18.0-alpha (but doesn't exist since 1.16.0-alpha)
OS: Ubuntu 20.04
Maven: 3.6.3

Hi Julien,
I have created a PR to fix this. The correction should be included in the next release which should take place in the next two weeks.
