Review IT cache invalidation

[matthieu-crouzet]

Context

Currently IT caches are invalidated if the source of a package or source of their explicit dependencies (package.json) has changed.
For example:
The IT of @ama-sdk/create needs to have @o3r-training/showcase-sdk published to access the exposed openapi.yml file. But @ama-sdk/create does not depend on @o3r-training/showcase-sdk, so when this package contains changes, it should invalidate the cache of @ama-sdk/create's IT.

Let's review our IT strategy so that we avoid relying on packages we do not have true dependency on.
