Fix excessive padding on terminal tool progress part action bar icons

[Copilot]

Action bar icons in the terminal tool progress part had excessive horizontal spacing due to .interactive-item-container .progress-container .codicon { margin: 0 .2em; } applying to all codicons, including those inside .monaco-action-bar.

Changes

• Add CSS rule in chatTerminalToolProgressPart.css to reset margin specifically for the terminal tool progress part action bar, matching standard action bar spacing

.chat-terminal-content-part .chat-terminal-action-bar .monaco-action-bar .codicon {
    margin: 0;
}

This scoped fix ensures only the chat terminal action bar icons are affected, without impacting other monaco action bars elsewhere in the UI.
