The "s_docs -l" command was identified broken recently by the open-source release process (see WT-13710 for details). To avoid breakage in the future, we should consider adding the command execution as an automated test and run it in Evergreen periodically.

It does not need to be run for every PR, probably not even worth running for every commit. There's an existing "~ Infrequent checks" build variant that might be best-suited to host this new test.
