## What changed?
<!-- Describe what has changed in this PR -->

WISOTT

PS: base-builder is already 1.23.2 (see
[link](https://github.com/temporalio/docker-builds/blob/ca17b250c72eb42018855c13d59588fb7229c4f4/docker/base-images/base-builder.Dockerfile#L4))

PPS: other docker-build jobs use this project's `go.mod` to install the
correct Go version (see
[search](https://github.com/search?q=repo%3Atemporalio%2Fdocker-builds%20go.mod&type=code))

PPPS: same for goreleaser (see
[link](https://github.com/temporalio/temporal/blob/main/.github/workflows/goreleaser.yml#L23))
