Use ENV.fetch to get HOST instead of relying on useless Sorbet error #1998

The auto-generated initializer has various starting time checks to prevent app misconfiguration before running. This did not apply to ShopifyAPI::Context's host: keyword. If the HOST env var was not present, a unhelpful "TypeError (Passed `nil` into T.must)" error was raised by Sorbet. Now if there is no HOST env var present, the app will fail to run, like it does with other checks, and the user will receive a helpful message.

There was a problem hiding this comment.
Maybe this is only a 90% improvement because what does Sorbet regurgitate when it's an empty string? A good ol user-raised ArgumentError or TypeError with a nice message is best but, this is quick and simple.
