Taxonomy terms in Route patterns not localized

[klickreflex]

Bug description

On a multi-site with multiple languages, I want to include an entry's assigned taxonomy term in its URL. Terms are translated, translated entries don't pick up the translated term slug in their routes.

How to reproduce

Concrete example:

• On a multisite setup, have a collection articles that uses a taxonomy categories.
• Each entry can have max. 1 term
• Set route pattern for articles to /{mount}/{categories}/{slug}
• Localize the terms' titles and slugs, e.g. travel becomes reisen in a German locale
• Create an entry in the articles collection, assign it a category and create a translation of it

Expectation:

• When an entry is viewed in German, I'd expect the Route to pick up the localized term slug reisen instead of travel

Reality:

• On every locale I get the source slug, e.g. /travel/tuscany-in-spring becomes de/travel/toskana-im-fruehling , when it should be de/reisen/toskana-im-fruehling

I've created a minimal setup to reproduce:

Ryan’s got an open PR for this #8627.

In the meantime, there is a workaround for this https://gist.github.com/jasonvarga/4342f96b77d52fcd27dad22d88253e1f.
