[Public Alert] Update env vars and config
remove custom mappings
Per Ursa's comment: !1077 (comment 1886255129)
remove custom mappings - AutomaticEnv
should already bind them to correct place and the duplicate alias just adds confusion. Example - without adding ensureBindEnv("webhooks.activity.slack", "PUBLIC_ALERT_WEBHOOKS_ACTIVITY_SLACK")
you can still set WEBHOOKS_ACTIVITY_SLACK=<webhook>
and then there's no ambiguity on what environment variable to use.
remove map in config struct
