Subject: [PATCH] Add a call to `clang --version` in the PR worfklow.

This change adds a call to `clang --version` after `swift --version` in the PR
workflow YML file. The result of this command is useful for investigating issues
stemming from out-of-date clang builds such as
https://github.com/swiftlang/swift-testing/pull/1320.
