CI: Upgrade GNU Toolchain Versions for Arm32/Arm64

[jserv]

Currently, the pre-built GNU toolchain for Arm-based CPUs used in our GitHub Actions is version GCC 11.2-2022.02, sourced from the Arm Developer website. Given that a more recent version, 13.3.Rel1, is now available on the same website, it's prudent to update our CI pipeline to this latest version to ensure our testing environment remains up-to-date.
