MAINT: drop Python 3.8 support due to EOL (#365)

* DX: exclude `.constraints` dir from VS Code search * DX: remove `python.analysis.typeCheckingMode` VS Code setting * FIX: set correct Python version for GitLab CI * MAINT: modernize Python syntax to Python 3.9 * MAINT: ignore links to PRD * MAINT: update links to `TypeVar`
