Bug Summary

Describe the bug:

When the check to ensure oapi-codegen does not produce different changes than on the PR fails the message does not include the change differences in question.

To Reproduce:

Submit a PR with changes to any of the *.gen.go files that does not match what oapi-codegen v1.12.4 generates.

Expected behavior

Error message should produce the following if endpoint.gen.go does not match what is generated by oapi-codegen v1.12.4:

generated source does not match current changes
