Implement integration tests for the Kiota client generation

[andreaTP]

Feature or Problem Description

The "client generation" feature relies on compiling Kiota with wasm as a compilation target.
So far we have been relying on the fact that the upstream Blazor integration would have caught issues early.
According to this conversation this part of the code has been removed from the project and we should have some sort of E2E test to verify that client code generation still works.
Nice to have: the update to the latest Kiota versions should be automated.

Proposed Solution

Integrate Playwright tests on top of the new Integration Tests.

Additional Context

The repository that is building Kiota is this: https://github.com/Apicurio/apicurio-client-gen
