Add info about global headers in header dialog

[imolorhe]

Also reflect the enabled global headers in the header dialog

Hello @imolorhe, I am willing to work on this issue. I have gone through the code base and wanted to clarify certain things. Firstly, where exactly can I find the header dialog (did you mean the tags in the GitHub repo that give info), and by global headers did you mean packages that were enabled globally?

Hey, awesome! I'm not sure I completely understand the question but this is the header dialog component. Unlike the other (newer) dialog components, I haven't moved this into its own separate component file yet. Regarding the global header, I am referring to the special header environment variables that applies global headers when the environment is enabled.

Let me know if that answers your questions.
