fix: Correct swapped metric types in Postgres deployment guide

The metric types for `replication_bootstrap_rows_total` and
`replication_bootstrap_complete` were swapped. Per the source
implementation, `replication_bootstrap_rows_total` is an
ObservableCounter (not ObservableGauge) and
`replication_bootstrap_complete` is an ObservableGauge (not
ObservableCounter).
