fix: mergeArraysBy generic return type.

- Fixed `mergeArraysBy` util function call in `Configuration::setLanguageConfiguration` method to pass its generic return type as vscode's `AutoClosingPair` or `OnEnterRule`. The function is declared with a passable generic `T` type, but it wasn't being used, so we might as well use it and pass the return types.
