2configs.services.matrix.bridges.mautrix-discord: grant synapse mautrix-discord group
Upstream creates /var/lib/mautrix-discord at mode 0770 owned by
mautrix-discord:mautrix-discord, but only adds matrix-synapse to the
mautrix-discord-registration supplementary group. That left synapse
unable to traverse the directory to read discord-registration.yaml,
crashing matrix-synapse on startup.
