Update go container image used to build bbctl
General MR
Summary
Update the bbctl build pipeline to use a later Golang image from IronBank rather than an older, public image.
This will bring the pipeline up to date with the Go version this MR is updating the bbctl
binary to, as well as hopefully resolve big-bang/product/packages/bbctl#43 (closed) without requiring a Kyverno policy update.
