[Bug] nacos-sdk-python 3.0.4 depends on a2a>=0.44

[bbslab]

ERROR: Cannot install nacos-maintainer-sdk-python because these package versions have conflicting dependencies.

The conflict is caused by:
nacos-sdk-python 3.0.4 depends on a2a>=0.44
nacos-sdk-python 3.0.3 depends on a2a>=0.44

Additionally, some packages in these conflicts have no matching distributions available for your environment:
a2a

To fix this you could try to:

1. loosen the range of package versions you've specified
2. remove package versions to allow pip to attempt to solve the dependency conflict
