Consume OpenIddict 7 client-assertion preview of Eryph.IdentityModel.Clients

Bump Eryph.IdentityModel.Clients to the preview build that negotiates the
client-assertion audience via discovery (eryph-org/dotnet-identitymodel#42), so
the new auth flows through ClientRuntime for end-to-end testing against an
OpenIddict 7 eryph server. Pinned to the PR preview on the dbosoft feed; to be
re-pinned to the released version once dotnet-identitymodel#42 merges.
