[one] Add ROS2 devcontainers and ONE-docker docs

[fnalmeidap]

Problem: RobôCIn does not have ROS2 devcontainers and has many different docker image implementations not published to RobôCIn's Docker Hub.

Solution:

1. Create docker images to be used as devcontainers for ROS2 with and without UI dependent scenarios.
2. Create base requirement documentation for ONE RobôCIn effort related to docker.
3. /containers repository has Docker Hub secrets, which enables publishing via GH Actions easily. This is preferable than adding secrets to every other repository that has docker images, thus centralizing this repo as a source of all RoboCIn dockerfiles seems as an adequate solution.

Images builds successfully:
