Fix x86_64 build in the CI release pipeline (#3033)

Fixes CI pipeline issues that occurred during the 0.44.0 release ([see
this actions
run](https://github.com/FuelLabs/fuel-core/actions/runs/15260746240/job/43155736997)).
Turns out the Linux version used by the default cargo cross image has an
outdated and known-buggy GCC version. Compiling everything under a
recent unmodified Ubuntu just works. I fixed the release itself
manually, and this PR simply changes the CI pipeline to not produce that
issue in the future.
