Spec Module (/packages/spec): Fix typo in `resolveOverridenLocale` function name

[7hacker]

The function resolveOverridenLocale appears to have a spelling error - "Overriden" should be "Overridden". This would involve:

1. Renaming the function
2. Updating all references to maintain backward compatibility
