make: Remove trailing _html from doc dir URLs

mavit · tarsius · commit 04b074dd9c2e · 2025-07-03T00:34:00.000+02:00
Fixes a broken link from [1] to non-existent page [2]. This is required because `makeinfo' expects linked HTML documents to be in a directory with a name ending "_html" (see [3]) but we don’t observe that convention.
