Ensure all `server/ql/*/tools/src/*/*.ql` queries have `server/ql/*/tools/src/*/*.md` documentation

[data-douser]

All server/ql/*/tools/src/*/*.ql queries must have accompanying server/ql/*/tools/src/*/*.md query documentation, using markdown format with a .md file extension instead of the XML-based .qhelp format.

There is a standard format -- including required sections as well as suggested style -- for such CodeQL query documentation.

For more context, see the CodeQL query-help style guide as well as existing query documentation in this repository, such as in server/ql/ruby/tools/src/PrintCFG/PrintCFG.md.
