feat: Toolbox product usage tracking UX part

[tbwiss]

RFC: #2051

This is the first part of the Toolbox product usage tracking task. It contains:

• An alert (using the neo4h NDL component) to highlight that product usage tracking is enabled by default
• A setting option to enable/disable product usage tracking at any time
• The basic setup for invoking Segment analytics and sending product usage tracking events to Segment
• A way to provide the keys for the two Segment sources (PROD and DEV) both for local usage as well as in GHA
• E2E test to verify the enabling/disabling of the product usage tracking

NOTE:
Until this point, only a dummy product usage tracking event has been set up, when one clicks the "star" to store the type definitions as a favorite, to verify if the event gets sent to Segment.
-> Both the DEV and the PROD Segment source receive the (dummy) product usage tracking events, this has been verified.

The rest of the product usage tracking events will be added in the next PR.
