[Fix] point cloud export broken in Dockerfile (#1148)

* Added Dockerfile to build docker image including all dependencies and nerfstudio, added description on how to user docker.

* Move docker description to Installation.md.

* Fix mask_filename indices after splitting train set.

* Rebase DOckerfile to newer image for updated libraries.

* Update docker container documentation.

 ## Use docker image
 Instead of installing and compiling prerequisites, setting up the environment and installing dependencies, a ready to use docker image is provided. \
 ### Prerequisites
-Docker ([get docker](https://docs.docker.com/get-docker/)) and nvidia GPU drivers ([get nvidia drivers](https://www.nvidia.de/Download/index.aspx?lang=de)), capable of working with CUDA 11.3, must be installed.

 The docker image can then either be pulled from [here](https://hub.docker.com/r/dromni/nerfstudio/tags) (replace <version> with the actual version, e.g. 0.1.10)

 ### Call nerfstudio commands directly
 Besides, the container can also directly be used by adding the nerfstudio command to the end.
 ```bash
-docker run --gpus all -v /folder/of/your/data:/workspace/ -v /home/<YOUR_USER>/.cache/:/home/user/.cache/ -p 7007:7007 --rm # Parameters.
+docker run --gpus all -v /folder/of/your/data:/workspace/ -v /home/<YOUR_USER>/.cache/:/home/user/.cache/ -p 7007:7007 --rm -it # Parameters.

 ```
 ### Note
 - The container works on Linux and Windows, depending on your OS some additional setup steps might be required to provide access to your GPU inside containers.
+- Paths on Windows use backslash '\\' while unix based systems use a frontslash '/' for paths, where backslashes might require an escape character depending on where they are used (e.g. C:\\\\folder1\\\\folder2...). Ensure to use the correct paths when mounting folders or providing paths as parameters.
 - Everything inside the container, what is not in a mounted folder (workspace in the above example), will be permanently removed after destroying the container. Always do all your tasks and output folder in workdir!
-- The user inside the container is called user and is mapped to the local user with ID 1000 (usually the first non-root user on Linux systems).
-- The container currently is based on nvidia:cudagl-11.3.1, consequently it comes with CUDA 11.3 which must be supported by the nvidia driver. No local CUDA installation is required or will be affected by using the docker image.
+- The user inside the container is called 'user' and is mapped to the local user with ID 1000 (usually the first non-root user on Linux systems).
+- The container currently is based on nvidia/cuda:11.7.1-devel-ubuntu22.04, consequently it comes with CUDA 11.7 which must be supported by the nvidia driver. No local CUDA installation is required or will be affected by using the docker image.
+- The docker image (respectively Ubuntu 22.04) comes with Python3.10, no older version of Python is installed.
+- If you call the container with commands directly, you still might want to add the interactive terminal ('-it') flag to get live log outputs of the nerfstudio scripts. In case the container is used in an automated environment the flag should be discarded.
