[`flake8-type-checking`] Make example error out-of-the-box (`TC001`) (#19151)
## Summary
Part of #18972
This PR makes [typing-only-first-party-import
(TC001)](https://docs.astral.sh/ruff/rules/typing-only-first-party-import/#typing-only-first-party-import-tc001)'s
example error out-of-the-box. The old example raised `TC002` instead of
`TC001`, so this makes it a `from .` import to fix that.
[Old example](https://play.ruff.rs/1fdbb293-86fc-4ed2-b2ff-b4836cea0c59)
```py
from __future__ import annotations
import local_module
def func(sized: local_module.Container) -> int:
return len(sized)
```
[New example](https://play.ruff.rs/b886535c-9203-48bb-812b-1aa306f2c287)
```py
from __future__ import annotations
from . import local_module
def func(sized: local_module.Container) -> int:
return len(sized)
```
The "Use instead" section was also modified similarly.
