Add ty checks

[adamtheturtle]

Note

Adds ty static checks to pre-push (including docs runner), adds its dev dependency, updates spelling dictionary, and annotates upload.py with targeted ty ignores.

• Tooling/CI:
  • Add ty and ty-docs pre-push hooks in .pre-commit-config.yaml and include them in CI skip list.
• Dependencies:
  • Add ty==0.0.1a34 to optional-dependencies.dev in pyproject.toml.
• Code (type-checking):
  • In src/_notion_scripts/upload.py, wrap UnoObjAPIBlock.model_validate(...) calls with comments and # ty: ignore[invalid-argument-type] at multiple sites.
• Spelling:
  • Add ty to spelling_private_dict.txt.
