fix: linter error (#246)

Fix linter error

<!-- greptile_comment -->

## Greptile Summary

Updates variable naming in `common/docker/client_image.go` to fix linter errors by renaming duplicate 'ok' variables in type assertions within the parseNonBuildkitResp function.

- Improved code clarity by using distinct variable names (ok2, ok3) instead of reusing 'ok' for multiple type assertions in error handling flow
- Change maintains existing functionality while addressing linter warnings for Docker build output processing
