Enforce response keys in openapi if possible

Overview

Follow-up to 🐛 Openapi.yml uses patternProperties which is not supported by our dependencies Needs work
IN that issue we removed and forbid the use of `patternProperties because didn't actually worked caused some of responses not to validated at all

Proposed resolution

Figure a way to validates, if we think this is still valuable.

We could do something like I tried in this MR https://git.drupalcode.org/project/experience_builder/-/merge_requests/226

Or simply put a hardcoded lists of routes and key patterns in ApiResponseValidator
