Add Cloud Run job link

[Nagai-Ryo-33]

This PR introduces a new helper class for constructing Cloud Run Job Execution Links and integrates it into the existing Cloud Run operators in the Google Cloud provider for Airflow. The most important changes
include the addition of the CloudRunJobExecutionLink class, its integration into the CloudRunExecuteJobOperator, and the necessary imports and configurations.

New feature addition:

• Added CLOUD_RUN_JOB_EXECUTION_LINK constant to construct URLs for Cloud Run Job Execution Links in airflow/providers/google/cloud/links/cloud_run.py
• Created CloudRunJobExecutionLink class to handle the construction and persistence of Cloud Run Job Execution Links in airflow/providers/google/cloud/links/cloud_run.py

Integration into existing operators:

• Imported CloudRunJobExecutionLink in airflow/providers/google/cloud/operators/cloud_run.py to make it available for use in Cloud Run operators
• Updated operator_extra_links in CloudRunExecuteJobOperator to include CloudRunJobExecutionLink in airflow/providers/google/cloud/operators/cloud_run.py
• Added logic to persist Cloud Run Job Execution Links in the execute method of CloudRunExecuteJobOperator in airflow/providers/google/cloud/operators/cloud_run.py

Configuration update:

• Added CloudRunJobExecutionLink to the extra-links section in airflow/providers/google/provider.yaml to ensure it is recognized as an extra link

Screenshot:
The new "Cloud Run Job Execution" link appears in the Extra Links section of the task details page, alongside the existing "Cloud Run Job Logging" link.

Hi there!
Thank you for the changes
There is a PR #51576 with changing the way we create links in google-provider, so I think you will need to rebase and change the links in your PR after our links refactoring will be merged.
