[docs-scanner] Time-relative language in Bake contexts documentation

[docker-agent]

File: content/manuals/build/bake/contexts.md

Issue

The documentation contains time-relative language that violates the style guide and will become stale:

As of Buildx version 0.17.0 and later, Bake automatically de-duplicates context transfer for targets that share the same context.

The phrase "As of" is time-relative language that the style guide prohibits because it goes stale silently. This framing suggests the feature is new, but will become outdated as time passes.

Suggested fix

Rewrite to state the current behavior without time references:

"Buildx version 0.17.0 and later automatically de-duplicates context transfer for targets that share the same context."

Or simply state the requirement:

"To automatically de-duplicate context transfer, you need Buildx version 0.17.0 or later, BuildKit version 0.16.0 or later, and Dockerfile syntax docker/dockerfile:1.10 or later."
