fix(eventstore): set application name during push to instance id (#8918)

Browse Source 
# Which Problems Are Solved

Noisy neighbours can introduce projection latencies because the
projections only query events older than the start timestamp of the
oldest push transaction.

# How the Problems Are Solved

During push we set the application name to
`zitadel_es_pusher_<instance_id>` instead of `zitadel_es_pusher` which
is used to query events by projections.
