* Added template base type
Proposition to add typing, as pre-commit test on newly created integrations fails on it automatically:
```
homeassistant/components/<my_integration>/__init__.py:11: error: Need type annotation for "PLATFORMS" (hint: "PLATFORMS: List[<type>] = ...") [var-annotated]
Found 1 error in 1 file (checked 4 source files)
```
I believe there shouldn't be other type than text, hence the proposition.
* Apply suggestions from code review
