Refactor NhlGameService and update PlayerTests

Refactored NhlGameService to use concise object initialization with `new()` syntax for `_nhlScoresHtmlReportsApiHttpClient`. Changed `CalculateMultiplier` to a private static method. Added a `default` case in `PlayerTests` switch statement to throw `ArgumentException` for unmatched `query` values.
