During the POC phase, only the Scaffolder actions and JIRA OpenAPI specs have been incorporated in the editor to enable function autocompletion.

The editor itself is already prepared and fetching specs from the backend through `getSpecs` (see plugins/orchestrator/src/api/api.ts) but the backend is hardcoding only those two aforementioned specs (see listStoredSpecs in plugins/orchestrator-backend/src/service/WorkflowService.ts).

This is heavily dependent on the default repository we are using to load workflows and other assets (see https://github.com/tiagodolphine/backstage-orchestrator-workflows/tree/main/workflows/specs)

As users would be allowed to load multiple repositories in https://issues.redhat.com/browse/KOGITO-9873, we should create a generic mechanism that discovers all available specs and returns them to the front end.
