feat: migrate rabby to use hub

[arlert-armin]

Summary

Rabby has been migrated to hub.

Fixes # (issue)

• Added an optional switchOrAddNetwork parameter to the connect method. This change addresses the Rabby wallet’s behavior, which throws a different error code for "chain not found." Since other providers might exhibit similar inconsistencies, this optional callback allows custom handling of network switching or adding during connection.
