Fix artifacts dropdown for other pipelines tables

What does this MR do?

Related to #329798 (closed)

We changed the pipelines table to lazy load artifacts in the dropdown.

There are a few pages that use the pipelines table component that need to also provide the artifacts endpoint so that they can lazy load the artifacts properly.

• Commits pipelines tab
• Merge request show pipelines tab
• New merge request pipelines tab
