Relax Sync requirement for storage_objects_insert_ext_stream

[zackangelo]

The storage_objects_insert_ext_stream extension method for uploading a stream to GCS requires that the Stream is Sync. But there doesn't appear to be a need for it and prevents being able to easily proxy an incoming Body stream from axum (which is not Sync).

I can open a PR if we're okay with this change.

Right, thanks for reporting. It is an easy fix, I'll handle it with releasing the next version 👍🏻 with this PR:
#147

@zackangelo Seems in the version of Reqwest, this Sync is now required, so I have to revert this in 0.25.

They have removed it again in the last commits:
seanmonstar/reqwest#2361

As soon as they release it I'll relax it again.
