Merge branch '23325-pipeline-graph-hidden' into 'master'

Fix pipeline graph hidden on commit and mr pages

## What does this MR do?

Dynamically invokes `new gl.Pipelines();` when an MR `builds` tab is clicked.

Dispatches `new gl.Pipelines();` on a `commit#builds` page.

## Are there points in the code the reviewer needs to double check?

## Why was this MR needed?

The pipeline graph was hidden on commit and mr pages
