get_object_store() not exported

**Describe the bug**

The doc examples for object_store all reference a function `get_object_store()`. This function is not exported nor documented.

**To Reproduce**

1. Navigate to https://docs.rs/object_store observe the use of `get_object_store()` in the doc examples (first instance under "List objects")
2. Search for get_object_store() https://docs.rs/object_store/latest/object_store/index.html?search=get_object_store#conditional-put

**Expected behavior**

The function is documented and exported. Or, the function is not used. Or, the function is defined in the doc examples.

**Additional context**

Start with the object_store documentation examples linked in the issue and search the crate for get_object_store(). Confirm whether the examples reference an unavailable function; done means the examples no longer contain an unresolved reference and the chosen behavior is reflected in the documentation or exports.
