BDD test output should be abridged

[dannystaple]

The BDD output summary on a job run currently shows the full BDD image docker build. This should remain in the job log, but the summary should only show the following:

• That it built the docker image.
• Which tests it ran.

Example expected output

> orionrobots.github.io@1.0.0 test:bdd
> cucumber-js tests/staging/features --require tests/staging/step_definitions/**/*.js

.......

2 scenarios (2 passed)
7 steps (7 passed)
0m03.387s (executing steps: 0m03.198s)

This would skip the docker build section.

Acceptance criteria

• Docker image build log for BDD tests is not shown in the BDD test workflow summary
• Docker image build log for BDD tests is shown in the Job log where it ran
• The cucumber js section showing the number of tests that ran and that they passed is shown in the workflow summary
