mention operating system in hosting

[webmasterdevlin]

I made a mistake in choosing linux as my os. I didn't remember that linux azure function does not have the advance settings kudu. I can map the paths though to these below

• Windows Path: C:\home\data\pbimonitor
• Linux Equivalent: /home/data/pbimonitor
• Windows Path: C:\home\site\wwwroot\Scripts
• Linux Equivalent: /home/site/wwwroot/Scripts

But I am not sure if I will encounter any problems down the line so I am deleting my resources and creating another one in windows.
I will edit the README file then create a PR.
