doc[README][RTD]: Refactor README from RST to MarkDown and add jupyter usage installation instructions.

Description

• Added jupyter notebook installation instructions (i.e. pip install notebook==5.6.1)
• Moved README from RST to MarkDown for sanity.
• Updated RTD instructions as well for the jupyter part.
• Removed redundant instructions and collected the steps and bash code together.

How Has This Been Tested?

Relevant Documents (optional)

Types of changes

• Docs (changes to the documentation)
• Refactor (refactoring code with no functionality changes)
• Style (formatting changes only, no code changes)

 ## Installation using python virtual environment - recommended
 
-`pycalibration` uses the same version of Python as Karabo, which in June 2021
-updated to use Python 3.11. Currently the default python installation on Maxwell
+`pycalibration` uses Python 3.11. Currently the default python installation on Maxwell
 is still Python 3.9, so Python 3.11 needs to be loaded from a different
 location.
 
-Therefore `pyenv` is used, we provide a pyenv installation at
-`/gpfs/exfel/sw/calsoft/.pyenv` which we use to manage different versions of
-python. This can be activated with ``source /gpfs/exfel/sw/calsoft/.pyenv/bin/activate``
+We use `pyenv` to manage different Python versions. A pyenv installation is provided at
+`/gpfs/exfel/sw/calsoft/.pyenv`.
 
-A quick setup would be:
-
-1.  `source /gpfs/exfel/sw/calsoft/.pyenv/bin/activate`
-2.  `git clone ssh://git@git.xfel.eu:10022/detectors/pycalibration.git && cd pycalibration` -
-    clone the offline calibration package from EuXFEL GitLab
-3.  `pyenv shell 3.11.9` - load required version of python
-4.  `python3 -m venv .venv` - create the virtual environment
-5.  `source .venv/bin/activate` - activate the virtual environment
-6.  `python3 -m pip install --upgrade pip` - upgrade version of pip

+## Working with Jupyter Notebooks
+
+If you plan to work with Jupyter notebooks interactively, you have two main options:
+
+### Option 1: Install Jupyter Notebook locally
+
+if you prefer to run Jupyter notebooks on your local machine or on Maxwell, you can install the `notebook` package in your virtual environment:
+
+```bash
+python3 -m pip install notebook==6.5.1
+```
+
+After installation, you can start a Jupyter notebook server by running:
+
+```bash
+jupyter notebook
+```
+
+### Option 2: Use max-jhub (Recommended)
+
+Alternatively, we recommend using max-jhub, a JupyterHub instance available at DESY.
+This option provides a convenient web-based environment for running Jupyter notebooks without needing to set up everything locally.
+
+For detailed instructions on how to use max-jhub, please refer to these documentations:
+
+- [Max-jhub DESY Documentation](https://confluence.desy.de/display/MXW/JupyterHub+on+Maxwell)
+- [Max-jhub EuXFEL User Documentation](https://rtd.xfel.eu/docs/data-analysis-user-documentation/en/latest/jhub/#via-max-jhub-recommended)
+
+To use max-jhub effectively with pycalibration, make sure you've created an ipython kernel as
+described in the [Creating an ipython kernel for virtual environments](#creating-an-ipython-kernel-for-virtual-environments) section below.
