Make project configuration variables non-nullable by default
A project configuration variable with the NULL default value is naturally
assumed nullable, for example:
config [string] config.libhello.fallback_name ?= [null]
Otherwise, to make a project configuration nullable we use the `null`
variable attribute, for example:
config [string, null] config.libhello.fallback_name ?= "World"
