Fix requirement of object store for http-body-util

[agourlay]

Fix the compilation of the object store due to incorrect requirement.

When updating to object-store 0.12.0, I ran into a crate compilation failure.

error[E0599]: no method named `into_data_stream` found for struct `BoxBody` in the current scope

help: there is a method `into_raw` with a similar name

The method into_data_stream has been introduced in http-body-util in 0.1.2.

Therefore object store needs to have a precise patch version requirement.
