feat: add ui5 middleware code coverage

Allows client side code coverage generation for ES6+ code powered by https://github.com/SAP/ui5-tooling-extensions/tree/main/packages/middleware-code-coverage.

Projects generated for UI5 versions before 1.113.0 will stick to old "Blanket.js" based code coverage determination limited to ES5 language specification.
