test: add tests for fixed tool definitions

Problem: the config fixes in the previous commit had no test coverage
proving the definitions produce valid commands.

Solution: add opts (cwd, tmpdir) and assert_diag to the test helper.
Add tests for all 8 fixed tools using run_fmt/run_lint to exercise the
actual configs. Add pylint to pip.txt, hadolint to binary.txt,
shellcheck to the binary CI job, and new test-dotnet and test-ruby
CI jobs.
