0.25.3 breaking `get_auth_headers` in src/anthropic/lib/bedrock/_auth.py due to bad parameter name

[amiralik16]

anthropic-sdk-python/src/anthropic/lib/bedrock/_auth.py

Lines 44 to 49 in 7312e0a

	session = _get_session(
	region_name=region,
	aws_access_key_id=aws_access_key,
	aws_secret_access_key=aws_secret_key,
	aws_session_token=aws_session_token,
	)

passes region_name to _get_session whereas _get_session expects region. Leading to a :

.../lib/python3.10/site-packages/anthropic/lib/bedrock/_auth.py", line 44, in get_auth_headers
    session = _get_session(
TypeError: _get_session() got an unexpected keyword argument 'region_name'

The fix should be a one line change to pass the correct argument name.

Facing the same issue as above in 0.25.3

Sorry about this, I had no idea that functools.lru_cache discards the function signature...

We'll have a fix out shortly

this has been fixed in 0.25.4
