Improve inference of booleans to handle string representations

- To improve the boolean inference, we can say that if rows value counts fall into:
- `[1, True, "true", "True", "yes", "t", "T"]`
- `[0, False, "false", "False", "no", "f", "F"]`
- --> we should infer the Logical Type to be Boolean.
- This would prevent the following weird inference, where both columns are inferred to be categorical.
