fix: use local overlay package import in parse_test.go

[devin-ai-integration]

Summary

Fixes an incorrect import in overlay/parse_test.go. The test file was importing github.com/speakeasy-api/jsonpath/pkg/overlay (from the jsonpath repo) instead of the local github.com/speakeasy-api/openapi/overlay package.

Review & Testing Checklist for Human

• Verify that overlay.Format, overlay.Parse, and o.ToString() called in the test are the intended functions from the local overlay package (not different implementations from the jsonpath repo)
