Pull request overview

Fixes a bug in OlivePackageConfig.get_pass_module_config when a dotted pass path is provided, and corrects a typo in the default olive_config.json so supported_algorithms is properly populated for IncQuantization.

Changes:

• Fix get_pass_module_config to correctly parse dotted pass types via rsplit(".", 1).
• Correct supported_algrithms to supported_algorithms for IncQuantization in olive_config.json.
• Add unit tests covering dotted-path lookup and IncQuantization.supported_algorithms.
