[ty] Accept documented boolean and fractional Pydantic inputs (#27754)
## Summary
Previously, we rejected byte strings for Pydantic boolean fields and
`Fraction` instances for integer and floating-point fields, even though
Pydantic explicitly documents these conversions:
```python
from fractions import Fraction
from pydantic import BaseModel
class Model(BaseModel):
enabled: bool
count: int
ratio: float
Model(enabled=b"true", count=Fraction(2, 1), ratio=Fraction(1, 2))
```
We now include `bytes` in `LaxBool` and `Fraction` in `LaxInt` and
`LaxFloat`. These inputs are explicitly described in Pydantic's
[boolean](https://pydantic.dev/docs/validation/latest/api/pydantic/standard_library_types/#booleans),
[integer](https://pydantic.dev/docs/validation/latest/api/pydantic/standard_library_types/#integers),
and
[float](https://pydantic.dev/docs/validation/latest/api/pydantic/standard_library_types/#floats)
documentation, even though they are missing from its published
[conversion
table](https://pydantic.dev/docs/validation/latest/concepts/conversion_table/).
