nice! I have a few comments.

First, the banner headline is a bit outdated. It should be something like "ZenML abstracts the infrastructure complexity for ML Engineers without locking you into any vendor"

Second, this part of the README also needs an update.. it feels like its overloaded with information... maybe removing some things or restructuring might help?

@htahir1 I just pushed some changes to the header:

• Replaced the image with the new text.
• Moved the header image to the top.
• Changed the badges to make them more compact and changed the colors to our primary palette.
• Removed some of the contents as requested.
