Restricted datasets can't be used with the API notation

[betolink]

If we want to search for a dataset that's not publicly available

import earthaccess

auth = earthaccess.login()
results = earthaccess.search_datasets(
  short_name="RESTRICTED_DATA"
)

will always return zero, even though our user has the proper access permission. I think the reason is because we are not passing the authenticated session to hits() here:

earthaccess/earthaccess/search.py

Line 54 in dd61f23

def hits(self) -> int:

A fix would be to implement the method using the auth session.
