Update the new Pipeline Quickstart with the new content for 4.7.

The current quickstart CR is not up to date with the 4.7 & 4.8 Import from git pipeline flow. 

Actual:
Instructions are not up-to-date with the 4.7 flow. 

Expected: 
Update the content of this CR to match the current flow.

Additional Information:

NOTE: new content ** (TBD)

In 4.7 we are auto starting the pipeline when it is created from the import from git flow, which makes the `Starting your Pipeline`  Instructions no longer useful. We should change this to instructions to something like `Navigating to Details page` for exploring more actions such as stop, rerun, edit your pipeline, which will be more useful to the user in terms of discover-ability.
