Use Step Label as Page Title

We are using this patch and it is working as expected.

I can see the patch applied and on getFormPageTitle() method, I added a dummy text at the end of title being returned to confirm the Title is updated: return $steps[$step_id]['label'] . ' TEST';

In the attached image, I can see the title updated after following a commerce workflow.

Patch is applied with composer:

"drupal/commerce": {
                "3113563 - Use Step Label as Page Title": "https://www.drupal.org/files/issues/2020-02-13/3113563-step-label-as-page-title-2.patch"
            },

Discussed this with Ryan on Slack, perhaps we should mimic what we were doing in Commerce 1.x which is:
Checkout: [step label]. (We probably should wrap that in a t().

$this->t('Checkout: @step_label'); Thoughts?

The first comment mentions SEO which is not really a concern for checkout pages which are typically not indexed and shouldn't be.
