dietpi-software: Node.js: fix for 64-bit

libatomic is now required for all architectures, but preinstalled on ARMv6 from Bookworm on as libssl3 dependency.

Also hardcode version on ARMv6 Bookworm, since latest v20 (v20.19.5) depends on GLIBCXX_3.4.29 and GLIBCXX_3.4.30 now as well, making v20.19.4 the latest ARMv6 build supported on Bullseye.

 Bug fixes:
 - DietPi-Software | Jellyfin: Resolved an issue where the service start failed due to new strict space requirements for logging (512 MiB) and temporary directories (2 GiB). To support low RAM devices, we use /mnt/dietpi_userdata/jellyfin/log for log files, and a subdirectory in /mnt/dietpi_userdata/jellyfin/cache for temporary files, restoring behaviour from Jellyfin before v10.10. This can be adjusted in /etc/default/jellyfin.
+- DietPi-Software | Node.js: Resolved an issue where usage could have failed, including Node-RED, Blynk Server, and MineOS installation, since it requires libatomic now for all architectures. Many thanks to @devifast for reporting this issue: https://dietpi.com/forum/t/24574
 
 As always, many smaller code performance and stability improvements, visual and spelling fixes have been done, too much to list all of them here. Check out all code changes of this release on GitHub: https://github.com/MichaIng/DietPi/pull/XXXX
