11.0.5 release: bump version and finalize changelog (#925)

Bump __version__ in parsedmarc/constants.py from 11.0.4 to 11.0.5 and
rename the "## Unreleased" CHANGELOG heading to "## 11.0.5". The section
holds one bug fix: the PostgreSQL schema now indexes every foreign-key
column, fixing the Grafana "Aggregate Report Details" panel timeout (#923).
