Same the Url

## Summary: i found the /graphql path and /performance_report with the post method. when i will create page with name /graphql i am not allowed on the grounds it is reserved but i can create page with name performance_report. although both use the same method but only /graphql cannot be created. ## Shops Used to Test: https://linkpop.com/performance_report ## Steps To Reproduce: 1. login to https://linkpop.com 2. create page and use performance_report to profile page url. 3. and it will be created successfully Best Regards, @4bel ## Impact It is clear that /performance_report should not be used like /graphql.
