DIGITAL-772

Purpose

Changes dg_breadcrumb.module so that community node breadcrumbs append Community to the current page crumb, matching the H1.
Changes digital_gov.theme so that community node browser titles also use the same node title + Community text.

Deployment and testing

Navigate to /communities and check out the various communities and see if the breadcrumb and browser titles have the word Community properly appended.

It looks like this solves the problem and doesn't introduce new problems! Given that ...

Hear me out, what if we took both of these out and instead tracked down where "Community" is being added to the H1, and removed that. Then we have the content editors update the page headings.

I think that would be more understandable to everyone long-term.

I see the word being added in node/node--community.html.twig and that also looks like the only thing append_title_text is used for, so we could also remove that as a parameter.
