URL: https://github.com/apache/iceberg/issues/7746
### Apache Iceberg version

### Query engine
None
### Please describe the bug 🐞
I have typing-extensions 4.6.1, and this version caused pydantic to failed
when importing BooleanExpression from pyiceberg. Downgrading to
typing-extension 4.5.0
`
from pyiceberg.expressions import BooleanExpression
`
