Add Dynatrace as a Supported Analytics Tool

# Summary

Setting up, maintaining, and iterating on an instance of Backstage can be a large investment. To help measure return on this investment, Backstage comes with an event-based Analytics API that grants app integrators the flexibility to collect and analyze Backstage usage in the analytics tool of their choice, while providing plugin developers a standard interface for instrumenting key user interactions. Dynatrace is currently not supported analytics tools according to the Backstage [documentation](https://backstage.io/docs/plugins/analytics/).

## Feature Suggestion

Create a Analytics module for Dynatrace similar to the [analytics-module-matomo](https://github.com/janus-idp/backstage-plugins/blob/main/plugins/analytics-module-matomo/README.md)
