Code Review

This pull request adds Docker as a dependency to the developer guide. My review suggests a small improvement to the description to make it more comprehensive for new contributors by mentioning that Docker is used for both building images and running end-to-end tests.

[gemini-code-assist]

Thanks for adding this dependency. The PR description mentions that Docker is needed for end-to-end tests, which is a very important piece of information for developers. The current text only mentions building container images. To provide a more complete picture for new contributors, it would be beneficial to mention both purposes.

Suggested change

	- [**Docker**](https://www.docker.com/), to build the container images
	- [**Docker**](https://www.docker.com/), to build container images and run end-to-end tests
