Update documentation and docker image

[mrrevillo0815]

The ROS2 Support works great! Two things that would be good to change now:

• It would be just good to update the docker image on docker hub to use Pointcloudset 0.9.0
• In the documentation: add the information that, when using ros2, you should use the folder where the metadata and the ros2 bag file is and not the file itself. (Or change the code behavior to look for the metadata file in the same folder as the ros2bag file.)

Good to get feedback on the ROS2 support.

This is also related to #69 an issue with the GitHub action that builds the docker images.

Yes I will look into changing the code behavior or just update the documentation.

Now the new version 0.10.0 solves this. @mrrevillo0815 can you maybe point at the location in the documentation or make an PR?

Thank you for the Update, I am sure it will help the people that will use your tool in the future. 😊

Sadly I do not work with this setup anymore and do not have a PC where I can run this.

But I'll look over it when I find time during the Week! 😁
