Case Sensitivity Issue in Variable Usage in Readme

[sentemon]

The variable SupportedLanguages is declared with an uppercase 'S' but used with a lowercase 's', causing a compilation error.

Sample Code:

System.Collections.Generic.IEnumerable<SupportedLanguages> SupportedLanguages = await LibreTranslate.GetSupportedLanguagesAsync();
System.Console.WriteLine(Newtonsoft.Json.JsonConvert.SerializeObject(supportedLanguages, Newtonsoft.Json.Formatting.Indented));

Fix:
Change to:

System.Collections.Generic.IEnumerable<SupportedLanguages> *supportedLanguages = await LibreTranslate.GetSupportedLanguagesAsync();
System.Console.WriteLine(Newtonsoft.Json.JsonConvert.SerializeObject(supportedLanguages, Newtonsoft.Json.Formatting.Indented));
