[go] func build installs go twice?

[dprotaso]

I updated the go.mod file to set the go version to 1.25

I'm seeing go toolchain being downloaded twice now which seems unnecessary

We are in the middle of some buildpacks changes. I will check up on this after that change and revisit to see if its still an issue. Waiting to merge #3067
