We attempt to resolve the language name in this order 1. Based on debug adapter if they're for a singular language e.g. Delve 2. File extension if it exists 3. If a language name exists within a debug scenario's label In the future I want to use locators to also determine the language as well and refresh scenario list when a new scenario has been saved Release Notes: - N/A
