Migrate rolling build to 26.04 (#1493)

Updates the reusable Linux x64 CI workflow to run ROS 2 Rolling builds on an Ubuntu 26.04-based container and adjusts package selection for Electron test dependencies based on Ubuntu version.

**Changes:**
- Switch the ROS 2 Rolling matrix entry from `ubuntu:noble` to `ubuntu:resolute` (intended 26.04 migration).
- Update Electron test dependency installation to select `libasound2t64` on Ubuntu 24.04 and 26.04 via `VERSION_ID` detection.

Fix: #1458
