Oh. . And one other benefit of it will be that we will be able to get rid
of about 40% of the "Providers Manager" code. Currently, in Providers
manager we have a lot of "ifs" that make it possible to use providers in
breeze and local environment from the sources. In "production" installation
we are using "get_provider_info"  entry points to discover providers and
discover if provider is installed, but when you use current providers
installed in Breeze to inside "airflow", we rely on `provider.yaml` to be
present in the "airflow.providers.PROVIDER_ID" path - so we effectively
have two paths of discovering information about the providers installed.

After all providers are migrated to the new structure, all providers are
separate "distributions" - and when you run `uv sync`  (which will install
all providers thanks to workspace feature) or `pip install -e
./providers/aws` (which you will have to do manually to work on the
provider - if you use `pip` rather than uv) - then we will not have to use
the separate path to read provider.yaml, because the right entrypoint for
the provider will be installed as well - so we will be able to get rid of
quite some code that is currently only used in airflow development
environment.
