Fix Import errors for text extras in Scorers

---

Generated Summary:

• Refactored imports to be lazy-loaded where necessary, improving module load times and potentially reducing memory usage.
• Added type ignore comments to imports that may not be found, preventing type-checking errors while maintaining compatibility.
• Updated the exception handling for module imports across multiple scorer files, improving error messages for users when dependencies are missing.
• Cleaned up the pyproject.toml file by removing an outdated datasets dependency and adding a new datasets dependency with a specified range.
• Adjusted mypy configuration for better type checking by ignoring specific errors related to unused imports and untyped imports in the dreadnode.scorers module.

Potential impact:

• Should enhance runtime performance by deferring import execution.
• Increases clarity of error messages for missing dependencies, aiding in smoother developer experience.
• Maintains code structure and readiness for type checking in a more efficient manner.
