golang-osd-e2e: derive e2e Dockerfile WORKDIR from go.mod

[MitaliBhalla]

Summary

• golang-osd-e2e/update reads WORKDIR from go.mod module path instead of config/config.go OperatorName (fixes MCWV and any repo where those differ)
• Bump e2e builder images to Go 1.26 (rhel_9_1.26 / golang-1.26-openshift-4.22) to match current operator go.mod and Konflux .tekton BASE_IMAGE

Motivation

Hand-editing generated test/e2e/Dockerfile in consumer repos is fragile and gets flagged in review. MCWV e2e Konflux builds failed on Go 1.25 builder while go.mod is 1.26.

Test plan

• KONFLUX_BUILDS=true ./boilerplate/openshift/golang-osd-e2e/update POST on managed-cluster-validating-webhooks produces Dockerfile with correct module path and rhel_9_1.26 builder
• Spot-check another operator where OperatorName == repo name (no WORKDIR change expected)

Review skipped

Review was skipped due to path filters

⛔ Files ignored due to path filters (1)

• boilerplate/openshift/golang-osd-e2e/update is excluded by !boilerplate/**

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.
