TrinoContainer.get_connection_url() returns the internal port, not the mapped host port

TrinoContainer.get_connection_url() builds the URL as trino://{user}@{host}:{self.port}, and self.port is the fixed container-internal port set in __init__ (8080 by default). It's never resolved through get_exposed_port(). Since Docker maps that to a random host port, the URL this method returns can't actually connect to anything.

Repro (4.15.0):

from testcontainers.community.trino import TrinoContainer
from sqlalchemy import create_engine, text

with TrinoContainer() as trino:
    print(trino.port)                             # 8080
    print(trino.get_exposed_port(trino.port))      # the real mapped port, e.g. 58092
    print(trino.get_connection_url())              # trino://test@localhost:8080 - wrong

    engine = create_engine(trino.get_connection_url())
    with engine.connect() as conn:
        conn.execute(text("select 1"))             # ConnectionRefusedError / TrinoConnectionError

Building the URL manually with get_exposed_port() instead of self.port connects fine.

For comparison, CockroachDBContainer/CrateDBContainer don't have this problem since they route through _create_connection_url(), which does resolve the exposed port. Looks like an isolated miss in the Trino module rather than a pattern elsewhere.

Suggested fix, matching how the other modules do it:

def get_connection_url(self):
    return f"trino://{self.user}@{self.get_container_host_ip()}:{self.get_exposed_port(self.port)}"

Happy to open a PR with this if useful. Found it while wiring up a nightly testcontainers job for apache/superset's db engine spec tests.

Localiza la implementación de TrinoContainer y lee get_connection_url(), get_exposed_port() y los métodos de URL comparables de CockroachDBContainer o CrateDBContainer. Añade cobertura para el comportamiento de la URL con el puerto asignado y verifica que una conexión creada a partir de get_connection_url() llegue al contenedor de Trino en ejecución.
