/hold

For several reasons:

• Until we have checked with the release team that Go 1.19 is available: CWFCONF-3455 created and question asked internally.
• Until Trigger the IBM Cloud Image Workflow on PRs as well #6587 is merged, to check in CI that the IBM Cloud image can be built successfully

[rm3l]

/hold cancel

Removing the hold, since CWFCONF-3455 has been resolved and I've checked that Golang 1.19 was available internally.
Also rebased to test that the IBM Cloud image builds successfully (#6587).
