Incorrect responseMode param is sent in RPIframe's prompt=none authorize request

[brionmario]

Describe the issue:

Response mode query is send with a wrong casing to the RPIframe's prompt=none authorize request.

Reason

This seems to have been introduced with asgardeo/asgardeo-auth-spa-sdk@8b77734 change, and it was previously working fine due to the authparam transformation(https://github.com/asgardeo/asgardeo-auth-js-core/pull/203/files#diff-f34c1fc70c8dfe6982556af3ab69b70a42b7a68c9119cfa0bfa4716acd929750R120). This was removed with #208.

How to reproduce:

Enable OIDCSessionManagement in the SDK and inspect the prompt none requests from the RP Iframe.

Expected behavior:

responseMode should be response_mode and it should be query.
