make generated help files deterministic/reproduciblecp-22.05.6-1cp-22.05.5-2cp-22.05.5-1co-22.05.6-1

generate-id() is only stable within a single invocation, the results
vary from run to run, causing two builds of the same codebase result in
different output.
Due to help including snippets from different files, a simple count
won't be unique enough, but combining it with the sourcefile's topic-ID
does the trick.
