fix(workflows): use Ubuntu 22.04 for BFV legacy server testing

BFV (Battlefield: Vietnam) requires glibc 2.31 or older but Ubuntu 24.04
ships glibc 2.39, causing SteamCMD runtime failures.

Update details-check workflow to:
- Add runner field to matrix generation
- BFV uses ubuntu-22.04 (glibc 2.31 compatible)
- Other servers continue on ubuntu-latest (24.04)

This ensures BFV tests pass in CI while keeping modern servers on
current GitHub Actions runners.
