Add OS-Climate demo git repo to integration tests

[codificat]

Is your feature request related to a problem? Please describe.

As a Thoth developer I would like to ensure that the service being provided is and remains usable by "real-world" use cases.

For that, it might be good to add some "real-world" repository to the list of repos with which we run integration tests.

High-level Goals

Have relevant OS-Climate repositories be checked for thoth advise-ability as part of the integration tests

Additional context

As part of the CNBi functionality we want to deploy it to OS-Climate ODH and be used by their projects.

Acceptance Criteria

The following repositories are part of the regular integration test for thoth advise:

• https://github.com/os-climate/aicoe-osc-demo
• https://github.com/os-climate/data-platform-demo
