Refactor ToHttpMethod to use a dictionary for mappings

Browse Source 
Replaced the switch statement in the ToHttpMethod method with
a case-insensitive dictionary for mapping HTTP method strings
to HttpMethod objects. Introduced a private static dictionary
to store predefined HTTP methods, including the addition of
the CONNECT method. Improved performance and maintainability
by leveraging dictionary lookups for faster and cleaner code.
