chore: Update code generator and controller tools

[banjoh]

Description, Motivation and Context

Upgrade code-generator and controller-tools tools which troubleshoot used to generate code and open API schema docs. The changes between versions of the tools are not significant and the open API schema doc changes are just updates to description text of types

This change is needed to get make generate working on golang 1.22 cause the code generator is now pinned to v1.22
