Default quarkus.oidc.authentication.cookie-path to '/' and deprecate quarkus.oidc.authentication.restore-path-after-redirect

[sberyozkin]

Description
We can optimize on 2 properties:

quarkus.oidc.authentication.cookie-path=/
quarkus.oidc.authentication.redirect-path=/callback
quarkus.oidc.authentication.restore-path-after-redirect=false

quarkus.oidc.authentication.cookie-path=/ should be default as the users will likely spend some time first figuring out why the authentication is failing - due to a missing state cookie for ex and then having to set it to /.

and

quarkus.oidc.authentication.restore-path-after-redirect is simply redundant - if quarkus.oidc.authentication.redirect-path is set then the user will have to be returned to this path and if it is not set then the current request URI has to be restored.
