[ci] Bump hosted pool images to windows-2025 / macOS-15#1482
Merged
Conversation
The Microsoft-hosted `windows-2022` and `macOS-14` images are aging out: they have less capacity and surface deprecation warnings in pipeline runs. Bump to the current latest images (`windows-2025` and `macOS-15`) on the dnceng-public `Azure Pipelines` pool. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
