* Update docs/configuring-playbook-bridge-mautrix-discord.md

As our instruction on usage has been outdated compared to the latest one (cf. d33701428d/bridges/go/discord/authentication.md), let alone confusing in the first place as our instruction on logging in and bridging have been mixed, this commit updates our instruction based on the latest official one.
