Closes #9752

• Collapse multi-line docstrings to one plain line and add missing rule/attr docs so //tools/ci:starlark_docs_test passes (ran locally: PASSED).
• fsharp_bench takes keyword-only arguments after name; wrapper_signatures.sh passes on fsharp/rules/defs.bzl. The fsharp package is a deleted package in this checkout, so the sh_test itself was not run; the script was run directly.
• Not run: nested-Bazel and consumer tests.
• Note: wrapper_signatures.sh also flags php, ruby, zig, dart, elixir and perl bench wrappers; not part of this issue.
