Fix `Non-inherited new context` golang-ci linter reported issues

[containedctx](https://github.com/sivchari/containedctx) is a linter that detects struct contained context.Context field. This is discouraged technique in favor of passing context as first argument of method or function.

For rationale please read [Contexts and structs](https://go.dev/blog/context-and-structs) the Go blog post.

Start by running the containedctx linter in the YAKS repository and identify the reported locations. Inspect each affected struct and its surrounding usage before deciding the required changes. Done means the reported contained context issues are resolved and the relevant tests pass.
