fix(helm): use openid-configuration path for Helm test

[fty4]

When testing against the root path the server will return a 404 status code which results in an unsuccessful test:

$ helm test lab 
NAME: lab
LAST DEPLOYED: Fri Jun  2 09:13:17 2023
NAMESPACE: default
STATUS: deployed
REVISION: 1
TEST SUITE:     lab-dapsserver-test-connection
Last Started:   Fri Jun  2 09:16:46 2023
Last Completed: Fri Jun  2 09:16:51 2023
Phase:          Failed
Error: 1 error occurred:
        * pod lab-dapsserver-test-connection failed

When changing the endpoint to /.well-known/openid-configuration a HTTP/1.1 200 OK will be returned:

$ helm test lab                                  
NAME: lab
LAST DEPLOYED: Fri Jun  2 09:43:00 2023

Last Started:   Fri Jun  2 09:43:08 2023
