[devbox] update go to 1.25.0 and disable CGO to workaround clang linker error

[savil]

Summary

I will modify go.mod to have go 1.25.0 in a subsequent PR (or maybe release?). Because we have a dependency in our Github Action tests (e.g. Test Flake Build) on the devbox-install-action which pulls in an older version of devbox. We need the go.mod to work for that older version.

How was it tested?
