## What changed?
* updates goreleaser to v2
* add GHA for build admin-tools and server images within this repo.
`docker-builds` will only be used for building pre 1.30 images
* added GHA to promote docker builds from temporaliotest to temproalio
docker image repos
* trivy security scanning gates for image promotion (pulled rom
docker-builds repo). The gate can be overridden
## Why?
* we decided to move away from building images in `docker-builds`. The
complexity is not needed
* updates goreleaser to v2 because the v1 definitions might be no longer
supported at some point and this is a good time to do it
* I used go scripts for the more complex flows instead of js or bash so
we don't introduce another language contributors need to be familiar
with. IMO the js or bash I did use it simple enough to understand.
## How did you test it?
It passes in CI.
## Potential risks
* these build pipelines are only compatible with the new docker images.
* merging this PR may break our nightly tests. Will double check before
merging
* flows that are not triggered by opening a PR are untested and
therefore not completely validated
