Fixes flaky serverless reporting tests

[ymao1]

Fixes #237285

Summary

The serverless version of these tests were failing with Response aborted while reading the body errors, which means the report is short-circuiting before completing. I noticed a previous change #185878 to increase the time the test waits for a report to 10m however, the queue timeout for reporting was still set to the default 4m so this increases the queue timeout for reporting to 10m in these tests to give it more time to complete.

This should also address the following tests (all failed due to Response aborted while reading the body):

• Failing test: Serverless Security Platform API Integration Tests - Common Group 1.x-pack/platform/test/serverless/api_integration/test_suites/reporting/generate_csv_discover·ts - Reporting Generate CSV from SearchSource unquoted values Exports CSV with almost all fields when using fieldsFromSource #244269
• Failing test: Serverless Observability Platform API Integration Tests - Common Group 1.x-pack/platform/test/serverless/api_integration/test_suites/reporting/generate_csv_discover·ts - Reporting Generate CSV from SearchSource validation Searches large amount of data, stops at Max Size Reached #238317
• Failing test: Serverless Observability Platform API Integration Tests - Common Group 1.x-pack/platform/test/serverless/api_integration/test_suites/reporting/generate_csv_discover·ts - Reporting Generate CSV from SearchSource unquoted values Exports CSV with all fields when using defaults #238182
• Failing test: Serverless Observability Platform API Integration Tests - Common Group 1.x-pack/platform/test/serverless/api_integration/test_suites/reporting/generate_csv_discover·ts - Reporting Generate CSV from SearchSource exported CSV file matches snapshot #236220
