ResourceStringsAsyncUpload.upload seems broken in SDK 3.5.0

[mkarolin]

With Python 3.10, Transifex Python SDK 2.1.0 this works as expected:

transifex_api.ResourceStringsAsyncUpload.upload(resource, content)

However, after upgrading to Python 3.12.3, Transifex Python SDK 3.5.0 the same code that worked with SDK 2.1.0 produces the following error:
