Marketplace: Breadcrumb with long text padding / wrapping

- In your site, go to `Plugins`
- Search for `subscriptions`
- Click on `Paid Memberships Pro`

**Result:**
- The padding between the separators doesn't look great (perhaps adding `text-align: center` can help)
- The breadcrumb wraps and doesn't seem _professional_. Should we truncate it so that it doesn't wrap?

Reproduce the Marketplace path through Plugins, the subscriptions search, and Paid Memberships Pro, then locate the frontend breadcrumb component responsible for the displayed text. Compare its separator spacing and wrapping with the attached screenshot; done means the breadcrumb has balanced padding and a professional long-text treatment without unwanted wrapping.
