Add SHA-pinning comment to remaining third-party action examples

The "single specific Swift version" and "building and testing your code"
examples pin a third-party action by SHA but only carried the
not-certified disclaimer. Add the matching actions-use-sha-pinning-comment
reusable so every third-party block is consistent.

 ### Apple platforms
 
-To target a specific Apple platform, set the `type` input (`ios`, `watchos`, `tvos`, `visionos`, or `macos`) and, for simulator-based platforms, the `deviceName` and `osVersion`. To check which simulators and OS versions are preinstalled on each macOS runner, see [AUTOTITLE](/actions/using-github-hosted-runners/about-github-hosted-runners#supported-software). If the simulator runtime you request is not already installed on the runner, set `download-platform: true` so the action downloads it before testing.
