Install Firefox Multi-Account-Containers when "Containers" are specified

[rungitringit]

Hello,
I'm creating a policy for a Linux SOE which will be deployed as a part of an OS image. I love that I can specify some default Containers for the Firefox Multi-Account-Containers extension to get my users going in the right direction.

It's intuitive but I found that I also have to install the Multi-Account-Containers extension under ExtensionSettings. Why isn't it included if I'm specifying "Containers" in the policy?

    "ExtensionSettings": {
      "@testpilot-containers": {
        "installation_mode": "force_installed",
        "install_url": "https://addons.mozilla.org/firefox/downloads/latest/multi-account-containers/latest.xpi",
        "default_area": "navbar"

Please consider adding the above to the "ExtensionSettings" example, especially since the actual ID of the extension is unintuitive ("@testpilot-containers") and the download URL not clearly published.
I'd recommend leaving the example of UBlock Origin there as most people should install that too!

PS: Related issue in the extension's repo: mozilla/multi-account-containers#2565 ("Please add logic to skip the introductory text if the extension Multi-Account-Containers extension is installed via Firefox policies")

It would be awesome if you could work with the people building the Firefox policy templates to add the option to pre-configure which sites go in which containers, but that's another idea!

I've taken your advice about the example text. I'll talk to the developer about the other suggestion.
