Issue describing the changes in this PR

-> when local.settings.json is absent.
Scenario1: running 'func host start' will Display Available WorkerRuntime on the screen and user can select the Runtime from the list so the FUNCTION_WORKER_RUNTIME setting is added and start hosting the function app
Scenario2: running 'func host start --{WorkerRuntime}' will add FUNCTION_WORKER_RUNTIME setting and start hosting the function app.

resolves #3544

Thanks for working on this!
Could you also check if this approach works when the core tools are started by the Static Web Apps CLI?
I'm afraid the terminal might not be TTY in that case, and would then not allow user interactions.

SWA CLI is used in many of our samples along with the Functions emulators, so this would still remain an issue.
