Dynamic agent label with `hw.arch.x86&&sw.os.linux&&ci.agent.dynamic` doesn't work

[sophia-guo]

If no idle agent we'd like to trigger a dynamic agent for linux-x64 if specify label [hw.arch.x86&&sw.os.linux&&ci.agent.dynamic](https://ci.adoptium.net/label/hw.arch.x86&&sw.os.linux&&ci.agent.dynamic/). However no agent was triggered [hw.arch.x86&&sw.os.linux&&ci.agent.dynamic](https://ci.adoptium.net/view/Test_grinder/job/Grinder/8689/console) as expected. If the dynamic agents configuration has been changed?
