Fix failing lint checks and update broken typings

[michael-linnane-lrn]

This pull request introduces several improvements and fixes across the codebase, primarily focusing on enhanced type safety, expanded Data API support, and improved CI reliability. The most notable changes include stricter type checks for request handling, the addition of Data API configuration and demo, and fixes for mypy lint errors and missing type imports.

Type Safety and Request Handling Improvements

• Updated all checks for self.request in learnosity_sdk/request/init.py to use isinstance(self.request, dict) for safer type handling, preventing runtime errors and making the code more robust. [1] [2] [3] [4]

Data API Enhancements

• Added Data API configuration to request signatures and introduced a Data API demo to the standalone demos, expanding the SDK's capabilities.

CI and Linting Reliability

• Fixed mypy errors that were causing lint check failures during CI builds, ensuring smoother and more reliable automated testing.
• Added missing import for types-setuptools in setup.py to resolve type checking issues during testing.

Setup Script Improvements

• Explicitly typed the version dictionary in setup.py for better clarity and compatibility with type checkers.

Looks good to me 💪.

I had to make this fix during the hackathon for the Data API demo. Might be worth fixing here in this PR as well if updating the docs to mention Data API is added to the demos

Agreed to address the signature hashing bug in a separate PR
