Cedric Montfort d9d77bed82 Allow logout+jwt JWT type for reactive
The OIDC back-channel spec recommends using a logout token typ `logout+jwt`
(see [here](https://openid.net/specs/openid-connect-backchannel-1_0-final.html#LogoutToken).

Support of this type was recently added [on the servlet side]([on the Servlet side](9101bf1f7d)), so back
porting the same on the reactive side to close the gap.

Closes gh-15702
