Rauthy OIDC v0.19 — Better support for Solid and Matrix

With the now accepted RSA signatures for DPoP tokens, the ephemeral, dynamic clients and the basic serving of webid documents for each user, Rauthy should now fully support. Solid OIDC. This feature just needs some more real world testing with already existing applications though.

EVENT_MATRIX_ERROR_NO_PANICThis new config variable solves a possible chicken and egg problem, if you use a self-hosted Matrix server and Rauthy as its OIDC provider at the same time. If both services are offline, for instance because of a server reboot, you would not be able to start them.
