build(core) migrate Linux CI to newer GCC versions

Spasi · Spasi · commit dfd20ac2f1c2 · 2025-12-28T15:17:01.000+02:00
- x86_64 binaries are now built on AlmaLinux 8  (GLIBC 2.28) with GCC 15
- Other architectures are still on Ubuntu 22.04 (GLIBC 2.35) with GCC 12

This was a forced moved because projects like OpenAL Soft and bgfx make
use of C++20 features and GCC 11 started showing its age. However, there
should not be any problems with GLIBC incompatibilities, 2.28 is a good
baseline for active LTS versions of most popular distros.
