When updating cloud run jobs image, job task-timeout is reset to default value.

**Issue Description:**

When updating a Cloud Run job's image version using the gcloud run command with the gcr.io/google.com/cloudsdktool/cloud-sdk:alpine, the **task-timeout** parameter of the cloud run job is being reset to 10 minutes.

**Steps to Reproduce:**

Use the following command to update the Cloud Run job's image:

gcloud run jobs update "${CLOUDRUN_INSTANCE_NAME}" \
--image "${DOCKER_ROOT_IMAGE}" \
--region "${CLOUDRUN_REGION}" \
--project "${GCP_PROJECT_ID}"

**Expected Behavior:**
The timeout should retain its configured value during the image update process.

**Actual Behavior:**
The timeout is reset to 10 minutes.

**Environment:**

- gcr.io/google.com/cloudsdktool/cloud-sdk:slim
- gcloud GA version
- gitlab ci for running the update image step

**Additional Information:**
This behavior is causing issues in scenarios where a different timeout is configured, leading to unexpected behavior during the image update process.

**Workaround**
used gcr.io/google.com/cloudsdktool/cloud-sdk:alpine to maintain the **task-timeout** value.

Note:
Please let me know if any additional information or logs are required to investigate and resolve this issue.
