Kate Editor and LSP setup

After switching to Debian with KDE plasma, I tried Kate, KDE's default text editor. It has all the necessary features for a modern day text editor. I am not gonna talk about KDE's features or it's benefits. Visit their website to learn more about it or search online to know more. https://kate-editor.org/

Kate has LSP client feature. You can install your desired LSP server(s) and configure Kate. When I was configuring I could not find many resources online on how to configure Kate for your desired language's LSP. So this is to help anyone looking for same issue and to my future self when I need to setup it up again. I know for a fact that my goldfish memory will not remember all this steps in few weeks time.
