fix: OpenShift integration test failures

[michael-valdron]

Description of Changes

Fixes the ginkgo not found and other go failures by adding -mod=readonly to all ginkgo and go commands to ensure -mod=vendor is never set for go modules without a vendor directory.

Additional Fixes

• Pinned go stack versions to starter project tags that match the stack version number to address go version mismatching

Ignoring EC failure as the fix is blocked by this issue.

Hmmm.. this might need further investigation into what is going on, this change did fix this problem in my local testing using the openshift release image 😕

I'll put this PR in WIP for now.

Can reproduce error in latest fail under a local pull of the runner image:

+ go install github.com/onsi/ginkgo/v2/ginkgo@v2.19.0
go: github.com/onsi/ginkgo/v2/ginkgo@v2.19.0: cannot query module due to -mod=vendor

When I add -mod=readonly also to go install the problem is resolved:

+ go install -mod=readonly github.com/onsi/ginkgo/v2/ginkgo@v2.19.0
go: downloading github.com/onsi/ginkgo/v2 v2.19.0
go: downloading golang.org/x/tools v0.21.0
go: downloading github.com/go-task/slim-sprig/v3 v3.0.0
go: downloading github.com/google/pprof v0.0.0-20240424215950-a892ee059fd6

Examining the test log at the point of timeout, it looks like we need to reduce our stack versions being tested on.

Discovered non terminating issue with the Go stack starter project, waiting to revert recent changes: devfile-samples/devfile-stack-go#3

Discovered non terminating issue with the Go stack starter project, waiting to revert recent changes: devfile-samples/devfile-stack-go#3

Have instead decided to pin go stack versions to use stack version tags to fetch the proper revision of the starter project: e8df390
