This looks great @ArooshLele. One thing I'd consider is changing all references to "plugin" to "plug-in" per the Zowe style 🐱

Suggested change

	The App framework loads plugins from components such as extensions based on their enabled status in Zowe configuration. The server caches knowledge of these plugins in the `<workspaceDirectory>/app-server/plugins` folder. This location can be customized with the `components.app-server.pluginsDir` variable in the Zowe configuration file.
