Update defaults in docstring

[hutch3232]

Looks like the defaults were changed in #901 but docstring was missed.

It seems like the new release of botocore is incompatible with any but the newest aiobotocore, but the version constraints are not working right.

Perhaps should have this

--- a/.github/workflows/ci.yml
+++ b/.github/workflows/ci.yml
@@ -39,7 +39,6 @@ jobs:
         run: |
           pip install git+https://github.com/fsspec/filesystem_spec

-          pip install --upgrade "botocore" --no-deps
           pip install . --no-deps

as aiobotocore should bring in exactly the right version of botocore.

That change makes sense to me. I believe pips resolver does not take into account already existing package versions, so it is pretty easy to break compatibility. I think it's best to install all packages with one call to pip install (perhaps even using a requirements.in file if there are a lot).

In this case I think removing that one line makes perfect sense. I can do it if you'd like on this PR or another.
