Add More GHA Runners to CI

Add:

#### windows: -> `windows-11-arm`

https://github.blog/changelog/2025-04-14-windows-arm64-hosted-runners-now-available-in-public-preview/
____

#### macOS: -> `macos-15-intel`

>Apple has discontinued support for the x86_64 (Intel) architecture. GitHub will no longer support this architecture on macOS after the macOS 15 runner image is retired in Fall 2027. You should begin migrating your workloads to arm64-based (Apple Silicon) runners as soon as possible to prepare for this eventual deprecation.
