Deprecation warnings with PHP 8.4

[carbtest]

the real issue seems to be with apereo/phpcas which as of As of June 2024 is unmaintained.

Deprecated: phpCAS::client(): Implicitly marking parameter $sessionHandler as nullable is deprecated, the explicit nullable type must be used instead 

Deprecated: phpCAS::proxy(): Implicitly marking parameter $sessionHandler as nullable is deprecated, the explicit nullable type must be used instead 

Deprecated: CAS_Client::__construct(): Implicitly marking parameter $sessionHandler as nullable is deprecated, the explicit nullable type must be used instead

At this point, this may be the time to archive this repo and begin migrating to a new solution. This repo is heavily reliant on apereo/phpcas and provides nothing but an abstraction to the tool.

for what its worth i added a PR apereo/phpCAS#445
