Add Task Queue Priority and Worker Versioning as alternatives in task-routing docs

[Copilot]

The task-routing page's "Multiple priorities" and "Versioning" sections only described Task Queue-based approaches, omitting newer features that can replace or simplify those patterns.

Changes

• Multiple priorities: Added mention of Task Queue Priority as an alternative to spinning up one Task Queue + Worker pool per priority level — lets you handle prioritization within a single Task Queue.
• Versioning: Added mention of Worker Versioning as an alternative to using separate Task Queues for code versioning — supports Pinned and Auto-Upgrade Workflow behaviors without needing separate queues.

Notes to reviewers

Both additions are additive — the existing Task Queue-based approaches are preserved as the primary description, with the new features called out as alternatives.

Content Issue

Section: Multiple priorities https://docs.temporal.io/task-routing#multiple-priorities
I think we should mention task queue priority, which can be used instead of creating several task queues.

section Versioning https://docs.temporal.io/task-routing#versioning
same here, we can mention worker versioning, which can be used to version "task queues."
