chore: add /v2 to import module path (#9072)

* chore: add /v2 to import module path

go mod requires semantic versioning with versions greater than 1.x

This was a mechanical update by running:
```
go install github.com/marwan-at-work/mod/cmd/mod@latest
mod upgrade
```

Migrate generated files to import /v2

* Fix gen
