chore(s4s): Remove s4s alerting for getsentry/sentry

[kenzoengineer]

We are deprecating s4s, which is causing a lot of noisy alerts in slack.

This PR removes mentions of s4s in sentry. In a later PR, we can remove it from sns (snuba, etc.)

[hubertdeng123]

should this be replaced with s4s2? or no

[kenzoengineer]

we have the 3 checks failing alert that covers s4s2 i think thats fine for now

we never had alerting for this for s4s2 to begin with and nobody has complianed
