Intergration tests `it/generate-code.ps1` does not fail if kiota generation fails.

Taking a look at the run at https://github.com/microsoft/kiota/actions/runs/7574601239/job/20646087900?pr=4027

The intergration tests for https://developers.pipedrive.com/docs/api/v1/openapi.yaml fail due to a a bad description. However the tests do not error out at this stage but continue to try to compile build a project with no generated code leading to a false positive.

We should

• [x] - Ensure it/generate-code.ps1 errors out on generation with non success exit code.
• [x] - Update the intergration tests config to exclude https://developers.pipedrive.com/docs/api/v1/openapi.yaml
• [x] - Investigate the issue with the description causing it to not be parsed right.

interestingly enough, there are suppressions for that API, but not for Java https://github.com/microsoft/kiota/blob/8f5d3b8fcb950bd6606c7ef04c71355a7de7c278/it/config.json#L120

The parsing issue is most likely caused by the fact this API has ambiguous path items (/foo/bar and /foo/{bar})

The description indeed has the duplicate paths as /oauth/token/ and /oauth/token. Authored https://github.com/microsoft/kiota/pull/4040 to resolve by adding an exclusion for the path.
