## Related Issue
Towards https://github.com/apache/airflow/issues/38195
## Why
DbApiHook's `get_uri()` incorrectly assumes Airflow Connection URIs are
valid SQLAlchemy URIs, which fails in complex cases, especially with special
characters. For `Trino`, the connection URI requires proper URL encoding and
specific handling of catalog/schema information.
This PR implements a robust `get_uri()` method in `TrinoHook` that correctly
formats `Trino` connection URIs with proper URL encoding of special characters.
## How
- Implemented `get_uri()` in `TrinoHook` with proper URL encoding using
quote_plus
- Handled schema information from both schema field and extra field
- Added unit tests for various connection scenarios
