chore(sentry): lower polling rates

As we're getting high loads on Sentry spans, we reduce the sampling rate
from 1.0 to 0.1 for production and 1.0 on staging.

The reason for this is to primarily lower the amount of traces sent.
However, we keep it 100% on staging to detect bugs and as traffic is
lower there
