Enable integration with the VS Code

- [ ] Scenario 1:
Developer copy existing folder -> Paste to new api-version -> make commit -> then update that swager
i.e braking change tool should work on previous commit v/s uncommitted changes

- [ ] Scenario 2:
Developer updates existing swagger inside a folder ->
i.e braking change tool should work on previous commit v/s uncommitted changes

- [ ] Tell me two commits and i'll work on it

Start by reviewing the existing command-line tool and how it compares two OpenAPI specifications. Define how VS Code should provide the previous commit and uncommitted changes for both listed scenarios, then verify that breaking changes are detected in each workflow.
