fix(amazonq): correct the isAutoTrigger boolean flag

[leigaol]

Problem

There is a bug in VS Code inline completion API, when hitting Enter, the context.triggerKind is Invoke (0)
when hitting other keystrokes, the context.triggerKind is Automatic (1)
we should only mark option + C as manual trigger Invoke(0)

Solution

Use timestamp to decide what is manual trigger and what is auto trigger.
