Always apply proxy configuration with MSAL for KiotaRequestAdapterHook in msgraph module (#61199)

* Update msgraph.py to_msal_proxies

Updated the logic of function to_msal_proxies. Return proxies attribute even when the authority is not filled

* Added Unit tests for testing to_msal_proxies.

* Changed elif to if based on Static Tests

* Removed trailing whitespaces based on Static Test output.
