Fix failing Azure tests (#19877)

This attempts to resolve these test failures by increasing the allotted time for the middleware when running on Azure. x-ref: https://dev.azure.com/nextjs/next.js/_build/results?buildId=22617&view=logs&jobId=5ee44de4-e310-59d9-0ba5-4a271a649fb0&j=5ee44de4-e310-59d9-0ba5-4a271a649fb0&t=af3fb693-3771-5a1a-ec97-2ba4cc77f25c x-ref: https://dev.azure.com/nextjs/next.js/_build/results?buildId=22619&view=logs&jobId=5ee44de4-e310-59d9-0ba5-4a271a649fb0&j=5ee44de4-e310-59d9-0ba5-4a271a649fb0&t=af3fb693-3771-5a1a-ec97-2ba4cc77f25c
