Backport PR #15921 to 8.12 branch, original message:

Updated the env2yaml to have a go.mod instead of relying on disabling go modules, otherwise building with golang 1.22 will fail.
This change also directly uses the golang image to build the binary removing the need for an intermediate image.

Tested locally and also with buildkite build docker image:

fixes #15920

Update the env2yaml to have a go.mod instead of relying on disabling go modules, otherwise building with golang 1.22 will fail in the future. This change also directly uses the golang image to build the binary removing the need for an intermediate image. (cherry picked from commit 5c3e64d)
