feat: add tracking for feature tab changes

[ckbedwell]

Problem

Currently, we don't track when users interact with feature tabs in the check editor sidepanel. This limits our ability to understand which features are being used and how users navigate between different feature tabs.

Solution

This PR adds tracking for feature tab changes in the check editor. When a user switches between feature tabs (such as Secrets, Docs, etc.), we now track this interaction with the feature_tab_changed event. The tracking includes the label of the selected tab and the source context (check_editor_sidepanel_feature_tabs), providing visibility into feature usage patterns.

The implementation:

• Adds a new tracking event function trackFeatureTabChanged in the check form events module
• Integrates the tracking into the FeatureTabsContext to automatically track tab changes
• Uses a callback wrapper to ensure tracking fires whenever a tab is activated

The label field in FeatureTabChanged interface is typed as FeatureTabLabel, which is ComponentProps<typeof Tab>['label']. This type can include React elements and other non-primitive values. However, TrackingEventProps only accepts boolean | string | number | undefined. This type mismatch could cause runtime issues if a tab label is anything other than a string or number.

Consider constraining the type to ensure only trackable values are accepted:

interface FeatureTabChanged extends TrackingEventProps {
  /** The label of the feature tab. */
  label: string;
}

Suggested change

	label: FeatureTabLabel;
	label: string;

Hmmm. Good point. We should change this to only allowing a string in the label prop. Will do that in another PR.
