rename to Installer ISO about live-iso

[porteusconf]

Maybe just a note would do. The name of the file is VanillaOS-2-stable.20240805.iso and I think no need to change the file name (or other names). Instead, perhaps just add a note to the readme.md something like this:

The iso for VanillaOS020stable boots to a gui-installer that includes gparted, but does not provide a full desktop environment like some other "live-iso" images you may have used. However the Recovery menu includes a Web Browser, Console (terminal), etc as well as Docs and Handbook. The install requires an internet connection, so connect an ethernet cable if you can. That said, lots of wifi hardware works, including pci/broadomm and most linux-compatible usb dongles. The "Connection Checker" step will verify your internet connection.
