detach mode seems not working with 0.3.5 release

👋 while bumping smug to 0.3.5 release, seeing some regression test issue with the detached mode

Hey. I think the problem is that the path is not correct. This patch should fix it

  test do
    (testpath/".config/smug/test.yml").write <<~EOF
      session: homebrew-test-session
      root: .
      windows:
        - name: test
    EOF

    assert_equal(version, shell_output(bin/"smug").lines.first.split("Version").last.chomp)

    with_env(TERM: "screen-256color") do
-      system bin/"smug", "start", "--file", testpath/"test.yml", "--detach"
+      system bin/"smug", "start", "--file", testpath/".config/smug/test.yml", "--detach"
    end

    assert_empty shell_output("tmux has-session -t homebrew-test-session")
    system "tmux", "kill-session", "-t", "homebrew-test-session"
  end

@ivaaaan sorry about the delay, and thanks for the pointer, I am gonna retry the PR now. 🙏

The error is different now that. I couldn't reproduce this with the test config on my machine. Help would be appreciated, I don't know much details on how homebrew runs its tests.
