telemetry(amazonq): add field to track auth type to metric

[dhasani23]

Problem

Want a field to track if user is authenticated with BuilderId or IdC for QCT.

Solution

Use an existing auth-related field and add it to an existing metric which will be emitted when /transform is invoked.

Here is the definition for that type:

        {
            "name": "enabledAuthConnections",
            "type": "string",
            "description": "Comma delimited list of enabled auth connections"
        },
        ```

Do we want to put it in projectDetails metric? The jobIsStartedFromChatPrompt and the isDoubleClickedToTrigger... metric names are slowly getting replaced by projectDetails.

[dhasani23]

Discussed in Slack: going to use jobIsStartedFromChatPrompt for now since projectDetails is always emitted on IDE startup; we want this metric to capture just users who tried transforming a valid project.

Tentative approval: moving discussion into slack

credentialSourceId can be used for that (awsId = "builder id"):
