Update go version for consistency

[nwnt]

The go versions in go.mod, go.work files are mismatched and causing the validation run in antithesis #20781 to fail (see here). Not sure if this is the right fix, but would love to hear your thoughts @joshjms @ivanvc.

I'm trying to understand why make build is breaking in that pull request. We have the pull-etcd-build tests and pull-etcd-release-tests that check this.

The go directive and the toolchain directive don't necessarily need to match. x-ref: #19423 (review).

[ivanvc]

Highly likely is this line:

etcd/tests/antithesis/server/Dockerfile

Line 47 in 116caca

RUN for d in server etcdutl etcdctl; do (cd ${d} && go mod tidy || true); done

There may be one dependency that it injects that requires 1.25.1.

[ivanvc]

The problem is with the Go environment variables in the Docker image. When the Antithesis code creates the new go.mod, it uses the GOVERSION and GOTOOLCHAIN environment variables. I have a fix for this, but it's not nice. I'll open a PR.

[nwnt]

Thanks @ivanvc! Will drop this one as yours has been merged
