`context["ti"].log_url` returns unuseable value

If "Other Airflow 2 version" selected, which one?

What happened?

The method get_log_url_from_ti of RuntimeTaskInstance contains a typo that returns an inaccessible URL.

The string is currently formatted;
_log_uri = f"{base_url}dags/{ti.dag_id}/runs/{run_id}/tasks/{ti.task_id}{map_index}{try_number}"

What you think should happen instead?

To correct this, a forward slash should be added
_log_uri = f"{base_url}/dags/{ti.dag_id}/runs/{run_id}/tasks/{ti.task_id}{map_index}{try_number}"

How to reproduce

The following dag code will print the url

from airflow.decorators import dag, task
from pendulum import datetime

@dag(
    start_date=datetime(2024, 1, 1),
    schedule="@daily",
    catchup=False,
    doc_md=__doc__,
    default_args={"retries": 3},
    tags=["example"],
)
def example_url():
    # Define tasks
    @task
    def print_log_url(**context) -> None:
        url = context["ti"].log_url
        print(f"log_url is {url}")

    print_log_url()
example_url()

The address produced returns an error
