Add Data lifecycle image and minor changes (#887)

* Add Data lifecycle image and minor changes

This change depends on the image upload PR #886
It adds the image to README, some minor readability changes, explanation of VDK in a separate sentence.

* Rename Data Lyfecycle to Data Journey

* Add the svg image github link

* Add data journey file to images

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Rename Data_journey.svg to versatile-data-kit-data-journey.svg

* Add the .svg file from the images folder

* Add data journey img for the dark mode

* Add dark mode image

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Replace an icon in the data journey img

 # Overview
 
-Versatile Data Kit is a framework which enables Data Engineers to develop, deploy, run and manage Data Jobs. **A Data Job is a data processing workload** and can be written in Python, SQL, or both at the same time. A Data Job enables Data Engineers to implement automated pull ingestion (E in ELT) and batch data transformation (T in ELT) into a database or any type of data storage.
+Versatile Data Kit (VDK) is an open source framework that enables anybody with basic SQL or Python knowledge to create their own data pipelines.

A Data Job enables Data Engineers to implement automated pull ingestion (E in ELT) and batch data transformation (T in ELT) into a database or any type of data storage.
 
 Versatile Data Kit consists of two main components:
 
-* A **Data SDK**, which provides all tools for the automation of data extraction, transformation and loading, as well as a plugin framework which allows users to extend the framework according to their specific requirements.
-* A **Control Service**, which allows users to create, deploy, manage and execute Data Jobs in Kubernetes runtime environment.

 To help solve common data engineering problems Versatile Data Kit:
-* allows ingestion of data from different sources including CSV files, JSON objects, data provided by REST API services, etc.;
-* ensures data applications are packaged, versioned and deployed correctly, while dealing with credentials, retries, reconnects, etc.;

 * provides built-in monitoring and smart notification capabilities;
-* tracks both code and data modifications and the relations between them enabling engineers to troubleshoot faster as well as providing an easy revert to a stable version.
