CLI issue form has duplicate terminal description key

What issue are you seeing?

The CLI issue form defines description twice for the same terminal-emulator input field:

  - type: input
    id: terminal
    attributes:
      label: What terminal emulator and version are you using (if applicable)?
      description: Also note any multiplexer in use (screen / tmux / zellij)
      description: |
        E.g, VSCode, Terminal.app, iTerm2, Ghostty, Windows Terminal (WSL / PowerShell)

In YAML, duplicate mapping keys are ambiguous and common parsers keep the latter value. In practice, the multiplexer guidance can be discarded by the second description key.

What steps can reproduce the bug?

1. Inspect .github/ISSUE_TEMPLATE/3-cli.yml.
2. Parse the issue templates with duplicate-key detection.

The duplicate is reported at lines 43 and 44 in the current template.

What is the expected behavior?

The terminal-emulator field should have one description key that preserves both pieces of guidance:

• ask for any multiplexer in use;
• provide examples such as VS Code, Terminal.app, iTerm2, Ghostty, and Windows Terminal.

Additional information

This is a small repo-metadata fix, not a runtime behavior change. A minimal patch would combine the two descriptions into one block scalar.

Because external PRs are invitation-only per docs/contributing.md, I am not opening an unsolicited PR, but I have the two-line template cleanup prepared locally if maintainers want it.
