Merge #7462

7462: Document running tests in parallel inside a dev environment r=deivid-rodriguez a=colby-swandale

### What was the end-user problem that led to this PR?

We do not have any documentation for running the test suite in parallel. Developers working on Bundler may be unaware that the test suite can be executed in parallel to help speed up the time needed to run tests.

### What is your fix for the problem, implemented in this PR?

Document how to run the parallel Bundler test suit in the Contributing docs.
