Upgrade @starknet-react/core dependency

[rsodre]

Request: upgrade package dependencies and examples@starknet-react/core to version 3.0.3

Reasoning: @starknet-react/core version 2 depends on starknet 5, and everybody's in starknet 6, even the controller.

Trying to upgrade my controller version 0.4.0 I get some build issues, related to that package.

If that is done, please test the examples, I think some hooks in v3 require the controller connector to support the request() function.

Install issues...
